Description

  The present invention relates to a technique for manufacturing an optical element and an optical element molding die with high accuracy, and to a system for supporting optical element design and manufacture.

  Conventionally, as the performance of various optical devices such as imaging cameras, laser beam printers, copiers, and semiconductor exposure devices has improved, there has been a demand for shape accuracy of optical elements such as lenses, mirrors, and prisms incorporated in these optical devices. It is becoming more sophisticated. Specifically, the shape of the optical element is complicated from a conventional flat surface, spherical surface, or axially symmetric aspherical surface to a free-form surface, and the required optical surface shape accuracy becomes stricter as the shape becomes more complicated. Furthermore, in order to achieve cost reductions associated with product cycle shortening and low cost competition, shortening of product manufacturing lead time is also required in optical element manufacturing.

  In recent years, not only in the optical element manufacturing field but also in a general part manufacturing field, various manufacturing support systems have been used in the part manufacturing process due to demands for high quality, low cost, and quick delivery. In particular, in the field of manufacturing general structure molding dies, the introduction of CAD / CAM is rapidly progressing. Here, the prior art of the manufacturing system centering on CAD / CAM in metal mold | die manufacture is demonstrated using FIG. 8 and FIG.

  FIG. 8 is a flowchart for explaining the mold manufacturing process. In FIG. 8, after starting the manufacturing process, first, a mold is designed in step S201. The mold design is performed using 3D CAD software, and the design drawing is saved as 3D CAD data. Based on the mold design 3D CAD data output in step S201, a mold machining process design is performed in step S202.

  In step S203, NC data required for machining apparatus control is generated based on the machining process designed in step S202. Specifically, the 3D CAD data output in step S201 and detailed machining conditions (apparatus control parameters) representing the machining process are input, and NC data is generated using CAM software.

  If the NC data is present, the machining apparatus used for the mold machining can be controlled, and the mold machining can be performed. However, the NC data generated in step S203 does not take into consideration the presence or absence of tool interference with the processing worker. Therefore, in order to avoid machining errors in die machining, it is necessary to confirm in advance the presence or absence of tool interference. Accordingly, in step S204, a machining simulation for verifying the presence or absence of tool interference is performed, and the NC data is corrected so that machining can be performed reliably.

  After NC data that can be reliably machined without causing a machining error is generated in step S204, die machining is performed in step S205. Here, there is a case where the machining operator reflects expert know-how and skill in the machining conditions and corrects detailed machining conditions that could not be reflected in the machining simulation. After completion of the die machining, machining information such as NC data corrected by the machining operator and used for actual die machining is registered in the machining performance database (step S206), and the die manufacturing process is completed.

  As a manufacturing system that supports the mold manufacturing process, a CAD / CAM system that can automate the data processing from steps S202 to S204 in FIG. 8 and generate NC data without human intervention has been put into practical use. Here, the automation of the data processing will be specifically described with reference to FIG.

  FIG. 9 is a diagram for explaining a process design tool used in the machining process design shown in step S202 of FIG. A process design tool 213 that is automatic design software for a machining process is connected to the machining apparatus database 211 and the machining performance database 212 via a computer network system. The processing apparatus database 211 is a database that stores apparatus specification information that summarizes the functions, performance, usage constraint conditions, and the like of a processing apparatus used for mold processing. The machining record database 212 is a database in which the machining record information registered in step S206 of FIG. 8 is stored. The process design tool 213 automatically acquires apparatus information and past machining record information necessary for performing process design from these databases, and automatically determines machining conditions based on the machining apparatus constraint condition and machining record.

Further, in FIG. 8, based on the machining process information automatically generated by the system configuration shown in FIG. 9 in step S202, NC data is generated in step S203 and machining simulation is sequentially processed in step S204. As described above, as a system that automates CAD / CAM data processing related to NC data generation from the creation of CAD data in step S201 to the die machining in step S205, for example, Japanese Patent Laid-Open No. 2006-98251 (Patent Document 1) or A system as disclosed in Non-Patent Document 1 can be mentioned. The system disclosed in Non-Patent Document 1 is characterized in that the system is constructed as a server / client type network application utilizing a Web service.

  When a manufacturing system similar to the above-described conventional mold manufacturing system is applied to the optical element manufacturing process, it is difficult to apply because of the following problems.

(1) Insufficient CAD data calculation accuracy Unlike general component manufacturing, optical element manufacturing requires shape accuracy on the order of nm on the optical surface. In particular, an optical element mounted on a semiconductor exposure apparatus or the like is required to have a highly accurate optical surface shape of 1 nm or less. On the other hand, the calculation accuracy guaranteed by general commercial 3D CAD software is currently on the order of μm, and the calculation accuracy is insufficient for the required accuracy of the optical surface shape.

  Also in the manufacture of optical elements, 3D CAD data is required in order to design a portion that can be handled with the same shape accuracy as a general manufacturing component, such as an optical element mounting reference surface for an optical device and an optical surface outer peripheral shape. At the same time, when designing an optical surface shape that requires shape accuracy on the order of nm, an optical surface shape calculation tool (software) that performs shape calculation from the same data as the data defining the mathematical formula is separately required. Thus, in the optical element manufacturing, the manufacturing process is realized by using the mathematical formula definition data and the 3D CAD data in combination as data representing the optical element design shape.

  On the other hand, as described above, also in the manufacture of optical elements, there is a demand for the introduction of a manufacturing system centered on CAD / CAM data processing, which has been introduced in the mold manufacturing field for general structures. However, since the optical element design shape data cannot be managed only by 3D CAD data, there is a problem that it is difficult to apply a conventional manufacturing system that has been put to practical use in the mold manufacturing field.

(2) Design constraints due to shape measuring equipment capable of measuring optical surface shape accuracy on the order of nanometers Contact type touch probe for shape measurement of general manufactured parts with required shape measurement accuracy on the order of μm A three-dimensional coordinate measuring apparatus equipped with is usually used. On the other hand, in the optical surface shape measurement process in optical element manufacturing, a high-accuracy three-dimensional shape measurement apparatus having a measurement accuracy on the order of nm is used. However, compared with the touch probe type three-dimensional coordinate measurement having the measurement accuracy of the μm order, the high-precision three-dimensional shape measuring apparatus having the measurement accuracy of the nm order is limited in the shape of the manufacturing part to be measured. Specifically, the inclination angle of the surface to be measured with respect to the probe contact direction, the local curvature of the surface to be measured, and the like are given as the shape constraint conditions.

  For example, as a device specification of a high-precision three-dimensional shape measuring apparatus that can be used for optical surface shape measurement, a measurable surface inclination angle to be measured is 60 degrees. At this time, if the shape of one optical surface to be measured as a continuous surface shape is not a shape in which the inclination angle is within ± 60 degrees in the region where the surface shape needs to be guaranteed, the shape measuring device measures It becomes impossible. In the production of optical elements, a highly accurate shape measurement step of the optical surface shape is essential for shape creation and quality assurance. Therefore, in order to establish optical element manufacture, an optical design that satisfies the above-described restrictions on the tilt angle of the optical surface must be made.

  Further, when measuring the optical surface shape of an optical element, it is set via a measuring jig or a measuring instrument when an optical element that is an object to be measured is attached to a normal shape measuring apparatus. The measurable inclination angle range, which is an apparatus restriction of the shape measuring apparatus, must consider the mounting posture of the surface to be measured with respect to the apparatus. Therefore, not only satisfy the constraints on the tilt angle of the optical surface to be measured in the optical design, but also meet the tilt angle constraint when attached to the shape measuring device via a measuring jig or hire Also, measuring jigs and hiring must be designed.

  On the other hand, the mold manufacturing system introduced in the mold manufacturing for the conventional general structure does not have a function to reflect the shape restriction caused by the shape measurement process in the mold design. In optical element manufacturing, it is essential to determine the shape constraints at the element design stage, measurement jig, and hiring design stage, so it is difficult to apply a conventional manufacturing system that has been put to practical use in the mold manufacturing field. There was a problem that there was.

  Due to the problems of (1) lack of CAD data calculation accuracy and (2) design constraints caused by the shape measuring device capable of measuring optical surface shape accuracy on the order of nm, a manufacturing system similar to the conventional mold manufacturing system is used. It is difficult to apply to optical element manufacture. With regard to (1), since data processing relating to the optical element design shape cannot be automated, it is necessary to perform processing manually through human intervention. For this reason, there is a high possibility that a return to the optical element manufacturing process will occur due to an artificial data input error, and in this case, there is a problem that the manufacturing delivery time is delayed. As for (2), measurement is impossible in the shape measurement process when the device constraint conditions in the shape measurement process, which is a subsequent process, are not considered in the design stage. Moreover, there is a possibility of causing a failure of the shape measuring apparatus. As a result, there is a problem that failure costs and production delivery delays occur in optical element manufacturing.

  The present invention has been made in view of the above-mentioned unsolved problems of the prior art, and provides a data management method and an optical element design / manufacturing support system that solve the problems (1) and (2). It is an object of the present invention to realize low cost and short delivery time of optical element products that have been impossible to realize by applying these systems to optical element manufacturing.

  In order to solve the above problems, an optical element design and manufacturing support system according to the present invention records optical element design shape data in an optical element design and manufacturing support system constructed as a network application connected to a computer network system. An optical element design shape database, a measurement jig for recording design geometry data of measurement jigs and measurement jobs, a measurement job database, a device constraint database of a shape measurement device used for optical element shape measurement, and the respective databases Based on the recorded data, calculation means for automatically determining the design constraint condition based on the measurement accuracy of the shape measuring device of the optical element and the optical element measuring jig and measurement, and output of the calculation result by the calculation means Providing an optical element design / manufacturing support system. To.

  The present invention automates the data processing of the shape measurement process in optical element manufacturing by associating and managing the mathematical expression definition data holding the optical element design shape information and the 3D CAD data in association with each other by the data management system. As a result, it is effective in that the measurement error caused by the data input error and the return due to the re-measurement which have occurred conventionally can be solved, and the low cost and short delivery time of the optical element can be realized. Further, by providing an optical element design environment, an optical element measurement jig, and an employment design environment that can refer to the design constraint information as network applications, it is possible to reliably satisfy the apparatus constraint conditions at the design stage. As a result, the return of the process due to redesign for satisfying the constraint conditions can be eliminated, and this is effective in that the low cost and short delivery time of the optical element can be realized.

  The best mode for carrying out the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram for explaining the system configuration of the optical element design and manufacturing support system according to the first embodiment of the present invention. The details of the optical element design / manufacturing support system provided by the present invention include an optical element design / manufacturing information integration system 50, a design shape data management system 51, a 3D CAD tool 52, and a constraint condition determination tool 53 as shown in FIG. As in the conventional mold manufacturing system, each subsystem and tool is connected via a computer network system, and is constructed as a so-called server / client network application.

  The optical element design / manufacturing information integration system 50 has a user interface function, and the user inputs / outputs various data necessary for the optical element design / manufacturing via the system. The optical element design / manufacturing information integration system 50 has a function of linking the subsystems and tools shown in FIG. For example, when data processing is performed on the optical element design shape 3D CAD data by the 3D CAD tool 52, 3D CAD data input / output to / from the 3D CAD tool 52 is performed via the optical element design manufacturing system 50.

  The design shape data management system 51 is represented as a subsystem of the optical element design / manufacturing information integration system 50. In the design shape data management system 51, an optical element design shape 3D CAD database (optical element design shape database) 10, an optical element design shape mathematical formula definition database 11, a measurement jig, a hiring design shape 3D CAD database measurement jig, (a measurement jig, The measurement employment database) 12 is managed. In particular, it is a feature of the present invention that the optical element design shape 3D CAD data that holds the design shape information of the optical element and the formula definition data that defines the optical effective surface shape are centrally managed. Various design shape data stored in the three databases include design shape management No. described later. Therefore, the relation is taken. That is, the design shape management No. The optical element design shape 3DCAD data of the corresponding optical element and the optical element design shape formula definition data are specified.

  The constraint condition determination tool 53 is directly connected to the shape measuring device constraint condition database 13 via a computer network system. Also, the system configuration is such that various design shape data can be acquired via the optical element design / manufacturing information integration system 50 and the design shape data management system 51.

  In FIG. 1, the optical element measurement system 54 is directly connected to the measurement condition database 14, the optical element measurement result database 15, and the measurement jig three-dimensional coordinate measurement database 16 via a computer network system. The design shape 3D CAD data in the measurement jig three-dimensional coordinate measurement database 16 is managed by the design shape data management system 51 described above.

  Next, the outline of the optical element design and manufacturing process by the optical element design and manufacturing support system of the present invention shown in FIG. 2 will be described.

  FIG. 2 is a flowchart for explaining an optical element design and manufacturing process according to an embodiment of the present invention. In the optical element design and manufacturing process according to the present invention, optical design is first performed in step S1. In step S1, an optical effective surface shape for the optical element to be manufactured to exhibit desired optical performance is designed using an optical CAD tool.

  Next, in step S2, it is confirmed by using a check tool described later whether the design constraint condition regarding the optical effective surface shape is satisfied with respect to the optical effective surface shape determined in step S1. The design constraint condition here is specifically a device constraint condition depending on the apparatus specification of the shape measuring apparatus used in the optical element shape measuring step performed in step S10 described later.

  In step S3, when the optical effective surface shape designed in step S1 satisfies the design constraint condition, the process proceeds to the optical element design (step S4) which is the next process according to the flow indicated by Yes. If the constraint condition cannot be satisfied, the flow indicated by No is followed to return to the optical design in step S1. In this case, the optical design is performed again to satisfy the design constraint conditions, and the optical effective surface shape is redesigned.

  In step S4, a shape other than the optical effective surface, such as a peripheral shape of the optical effective surface designed in step S1 and a shape to be an attachment portion when the optical element is mounted on the optical device, is designed using the 3D CAD tool. Although details regarding the 3D CAD tool will be described later, the optical element design tool is characterized in that the function provided by the present invention is added to commercially available 3D CAD software.

  In step S5, as in step S2, whether or not the optical element shape designed in step S4 satisfies the design constraint conditions related to the optical element shape is confirmed using a check tool described later. The design constraint conditions here are also the device constraint conditions of the shape measuring apparatus used in the optical element shape measuring step, as in step S2.

  Similar to the branch of step S3, also in step S6, if the optical element shape designed in step S5 clears the design constraint condition, the process proceeds according to the flow indicated by Yes. That is, the process proceeds to measurement jig, hiring design (step S7), and optical element production (step S8). On the other hand, when the constraint condition cannot be cleared, the process returns to the optical element design in step S4 by following the flow indicated by No. In this case, the optical element shape other than the optical effective surface shape is redesigned so as to clear the design constraint condition.

  In the optical element fabrication in step S8, an optical element is fabricated based on the optical effective surface shape determined in the previous step and the design value of the optical element shape including the portion other than the optical effective surface. As a specific manufacturing method, for example, a method by molding using an optical element molding die may be used. Alternatively, a method of directly processing an optical element material made of glass or the like to create a shape may be used. In the present invention, these optical element manufacturing methods are not limited.

  In step S7, according to the optical element design shape determined in the previous process, a measurement jig and a measurement job used in the optical element shape measurement process performed in step S10 described later are designed. At that time, the 3D CAD tool is used in the same manner as in step S4, and the 3D CAD tool here is also provided with a function provided by the present invention described later to the commercially available 3D CAD software in the same manner as the tool used in step S4. And

  When the design of the measurement jig and measurement job is completed, as in step S2 and step S5, whether or not the design constraint condition is satisfied for the measurement jig and job shape designed in step S7 is checked using a check tool described later. Confirm (step S9). The design constraint conditions here are also device constraint conditions of the shape measuring apparatus used in the optical element shape measurement process.

  In the branch of step S10, when the measurement jig and the hire shape designed in step S7 have cleared the design constraint conditions, the process proceeds according to the flow indicated by Yes. That is, the process proceeds to the measurement jig, hiring production (step S11), and measurement input data creation (step S12). On the other hand, if the constraint condition cannot be satisfied, the flow indicated by No is followed to return to the measurement jig / employment design process in step S7. In this case, the measurement jig and the measurement job are redesigned to clear the design constraint condition.

  In step S11, a measurement jig and a measurement job are manufactured based on the measurement jig and the design shape of the measurement job determined in the previous process. Here, the design shape of the measurement jig and the measurement job is stored as a file as 3D CAD data output as a result of designing using the 3D CAD tool. Using these CAD data files as input, a commercially available CAM tool is used to process and manufacture measurement jigs and measurement jobs.

  In parallel with step S11, in step S12, measurement input data necessary for the optical element shape measurement step in step S13, which is a subsequent step, is created. The data creation operation here is specifically performed using a measurement preparation tool which is one function of the optical element measurement system provided by the present invention. Details of the optical element measurement system and the measurement preparation tool will be described in the embodiments described later.

  After all of the optical element production in step S8, the measurement jig in step S11, the hiring production, and the measurement input data creation in step S12 are completed, the optical element shape measurement is finally performed in step S13. Specifically, a high-accuracy three-dimensional surface shape measurement apparatus having a measurement accuracy on the order of nm with respect to the optical effective surface shape is used to perform high-accuracy three-dimensional surface shape measurement. The surface shape measurement here is intended to obtain optical surface shape evaluation, which is indispensable in the optical element manufacturing process, and shape correction data when performing surface shape correction.

  The optical element manufacturing process according to the present invention ends when the optical element shape measurement in step S13 is completed.

  Next, details of each design process in the optical element design manufacturing flow shown in FIG. 2 will be described.

  In the optical design performed in step S1 of FIG. 2, an optical effective surface shape is designed using an optical CAD tool. In general, the design shape of the optical effective surface is defined by some continuous function. That is, when an orthogonal triaxial coordinate system (right-handed system) is set in which the optical axis direction of the optical effective surface is the Z axis, and the two axes perpendicular to the Z axis are the X axis and the Y axis, the optical effective surface shape is a continuous function. It is defined in the format z = f (x, y). Here, the optical effective surface shape is not always represented by a simple function z = f (x, y). For example, z = b (x, y) that defines the base surface shape and z = b (x, y) that defines z = c (x, y) that defines the microstructure modified on the base surface shape. , Y) + c (x, y). Furthermore, in the triaxial coordinate system that defines the optically effective surface shape, the shape definition function may differ depending on the XY region. That is, the shape of a certain area in one optical effective surface may be defined by z = s (x, y), and may be defined by z = t (x, y) in another adjacent area. In the present invention, these shape defining methods are not particularly limited. The optically effective surface shape only needs to be mathematically defined as some function of the abscissa (x, y) in the orthogonal triaxial coordinate system.

  As the design information of the optical effective surface shape designed in step S1, information representing the mathematical definition z = f (x, y) of the optical effective surface shape is output as a data file. The optical effective surface design shape information output from the optical CAD tool is generally composed of information relating to polynomial coefficients for defining mathematical formulas, coordinate conversion information of a coordinate system defining mathematical formulas, and the like. In the present invention, as the optical surface design shape data, a data file including mathematical expression definition information and coordinate conversion information output by an optical CAD tool is handled. Specifically, as shown in FIG. 3, a data file in which the value of a coefficient is set as a parameter 21 for a tag 20 representing a coefficient of a certain term in a mathematical expression defining an optical effective surface design shape. . The format of the optical effective surface design shape mathematical formula definition data file is preferably, for example, a tag using XML, a parameter structure data file, or the like, but the data file format is not particularly limited in the present invention. The optical element design / manufacturing support system provided by the present invention is characterized in that the optical effective surface design shape mathematical formula information is managed in a data file format unified in one specific format.

  The optical surface design shape formula definition data file output in step S1 is passed through the optical element design / manufacturing information integration system 50 shown in FIG. Data is output. The optical designer who is the system user inputs the optical element design shape formula definition data to the optical design manufacturing support system 50 as shown in FIG. 2, and the coefficient information and coordinates of the formula defining the optical effective surface design shape. The conversion information is output (saved) as a recorded data format.

  The data format of the optical element design shape mathematical formula definition database 11 may be a method based on internal data management of a general relational database or a method based on file management. In the present invention, these database formats are not limited. In the case of a method using a relational database, internal data analysis is performed on the optical effective surface design shape formula definition data file input from the optical element design / manufacturing information integration system 50 by the data management function provided in the design shape data management system 51. Is called. Based on the data analysis result, the data is output as internal data in the optical element design shape mathematical formula definition database.

  On the other hand, when the file management method is adopted, the design shape data management system 51 defines a file management rule that is determined from the relationship of the optical effective surface to the optical element. Based on this file management rule, the optical effective surface design shape formula definition data file input from the optical element design / manufacturing information integration system 50 is stored in the optical element design shape formula definition database 11 via the design shape data management system 51. Is output.

  Next, the design constraint condition check regarding the optical effective surface shape performed in step S2 is stored in the optical effective surface shape design information stored in the optical element design shape mathematical formula definition database 11 shown in FIG. It is done based on the information.

  An optical designer who is a system user activates the constraint condition determination tool 53 using the optical element design / manufacturing information integration system 50 as a user interface, and confirms the constraint conditions for the optical effective surface design shape designed in step S1. At this time, the constraint condition determination tool 53 extracts information related to the device constraint condition of the shape measuring device necessary for the determination from the shape measuring device constraint condition database 13. The optical effective surface design shape information to be determined is acquired from the optical element design shape formula definition database 11 via the design shape data management system 51. The constraint condition determination tool 53 includes calculation means for calculating the optical effective surface shape with respect to the optical effective surface design shape information input from the optical element design shape mathematical formula definition database 11. In the optical effective surface design shape calculated by the optical effective surface shape calculating means, for example, the maximum inclination angle in the optical effective surface can be measured by referring to the device constraint data extracted from the shape measuring device constraint database 13. It is determined whether it is within the tilt angle range. The determination result output from the constraint condition determination tool 53 is output to the system application screen via the optical element design / manufacturing information integration system 50. At the same time, the determination result is also output as internal data managed in the optical element design / manufacturing information integration system 50. In the case of the determination result NG, the process cannot proceed to the optical element design in step S4. That is, the optical element design / manufacturing information integration system 50 provided by the present invention has a function of controlling the workflow (process) shown in FIG. 2 based on the determination result output of the constraint condition determination tool 53. .

  In the design constraint condition determination in step S3, the optical element design / manufacturing information integration system 50 performs workflow control based on the determination result.

  Next, in the optical element design performed in step S4, the 3D CAD tool 52 shown in FIG. 1 is used to design an optical element shape other than the optically effective surface. The 3D CAD data file output as the optical element design information is output in the 3D CAD data format to the optical element design shape 3D CAD database 10 via the design shape data management system 51 via the optical element design / manufacturing information integration system 50. The The optical element designer as a system user may start the 3D CAD tool 52 using the optical element design / manufacturing information integration system 50 as a user interface and output design and design information (3D CAD data). Alternatively, the 3D CAD tool connected to the optical element design / manufacturing support system is directly started, and the command linked to the design shape data management system provided in the 3D CAD tool is directly operated, so that the design information (3D CAD data) is stored as data. The form which outputs may be sufficient. In the present invention, the 3D CAD data file output by the 3D CAD tool is stored in the optical element design shape 3D CAD database 10 managed by the design information data management system 51 via the optical element design / manufacturing information integration system 50. And

  Next, the design constraint condition check regarding the optical element shape performed in step S5 is based on the design information of the optical element shape stored in the optical element design shape 3DCAD database 10 and the information stored in the shape device constraint condition database 13. To be done. Similar to the design constraint condition check performed in step S2 and step S3 described above, the optical element designer who is a system user uses the optical element design / manufacturing information integration system 50 as a user interface and makes a determination using the constraint condition determination tool 53. At this time, the element design information 3DCAD data acquired from the optical element design shape 3DCAD database 10 is used as the design information, which is different from the steps S2 and S3.

  For the measurement jig and hiring design performed in step S7, 3D CAD data as design information is created as in step S4, and the data is output to the measuring jig and hiring design shape 3D CAD database 12 in FIG. The details of the 3D CAD tool used here are partially different from those of the 3D CAD tool used in the optical element design described above, but the form when data is output after the design is completed is the same as in step S4. Details of the functions of the 3D CAD tool will be described later with reference to FIG.

  The specific design constraint condition determination performed in this step includes, for example, a measurement probe interference check of a shape measuring apparatus used in optical element shape measurement. The constraint condition determination tool 53 is provided with probe interference check calculation means that receives 3D CAD data of optical element design information and probe shape 3D CAD data provided from the shape measurement apparatus constraint condition database 13. Here, the probe interference check with the optical effective surface adjacent to the optical effective surface serving as the measured surface or the probe interference check with the peripheral shape of the optical effective surface adjacent to the optical effective surface serving as the measured surface is performed. In the present invention, in the high-precision three-dimensional shape measuring apparatus used for measuring the optical effective surface shape, the contact type and the non-contact type are not particularly limited with respect to the probe type provided in the apparatus. In the case of using a shape measuring device including a contact probe, the probe shape itself is registered in the probe shape 3D CAD data. In the case of using a shape measuring apparatus including a non-contact type probe, a shape indicating a path region of a light wave irradiated from the non-contact probe is registered together with the probe shape.

  In the design constraint condition check regarding the optical element shape performed in step S5, a design constraint condition check for the size of the designed optical element shape is also performed. In this case, the constraint condition determination tool 53 includes a calculation unit that checks whether or not the shape measurement apparatus mountable work size acquired from the shape apparatus constraint condition database 13 is within the measurable optical element size.

  In the design constraint condition determination in step S6, the optical element design / manufacturing information integration system 50 performs workflow control based on the determination result, as in step S3.

  Next, the measurement jig and the design constraint condition check regarding employment performed in step S9 are substantially the same as the previous steps (steps S2 and S5) described so far. The design information that the constraint condition determination tool 53 receives as input data is different from the data acquisition from the optical jig design shape 3D CAD database 10 and the optical element design shape mathematical formula definition database 11 as well as from the measurement jig and the hiring design shape 3D CAD database 12. . Here, after reflecting the measurement jig and the shape of the measurement job, check the tilt angle of the surface to be measured performed in the preceding process, the measurement jig for the workpiece size that can be mounted on the shape measurement device, and the size check including employment I do. The point that the optical element design / manufacturing information integration system 50 performs workflow control based on the determination result is the same as the restriction condition determination step in the previous step.
