Description of the invention: [Technical field to which the invention pertains] In particular, it relates to a one-piece type. The present invention relates to a composite lock glass molded composite lens and a method of manufacturing the same. [Prior Art] - In the past, when manufacturing an optical element, it is not necessary to use a mold having a single mold core or a mold having a plurality of mold cores, which is common to φ. All of them make a single glass nitrate material into a single-optical component, the difference is only: the production of (four) the number of optical components in the same time. 'However, when the microscopic optical components are manufactured by the above method, for example, micro optical lenses (such as (10) Lens) and Micr〇Lens Array, the above-mentioned methods have the problem of not being able to effectively increase production and reduce costs. A forming system for a multi-optical element (U.S. Patent No. 2003/0115907 A1) discloses the use of a mold having a plurality of glass molds to form a shape, and a plurality of forming surfaces on the forming mold are written on A flat glass material preform to form a glass substrate having a plurality of optical elements. Such a conventional technique can form a glass mold of an optical element or a micro optical element using a simple flat glass-material preform, and has mass productivity and a low production cost, but the manufacturing process of the mold is complicated. 'When the individual optical elements are separated from the glass substrate, it is difficult to control the dimensional precision, and it is difficult to obtain a high precision optical glass element. In addition, as shown in FIG. 1 , a composite lens 4 is conventionally coated with a glue layer 3 on the surface of a first lens 1 and a second lens 2 5 201006770 on the glue layer 3 . After the first and second lenses 1 and 2 are adjusted so that the optical axes of the first and second lenses 2 are concentric, the adhesive layer 3 is cured by heating or uv light, that is, The composite lens 4 can be obtained by fixing the first and second lenses ^, 2 together. Although the manufacturing method can produce the composite lens 4' having the chromatic aberration compensation function, the manufacturing method and the composite lens 4 have the following defects when actually manufactured and used: The spear J is manufactured by the above method. In the case of the lens 4, it is necessary to perform the core-setting operation twice (refer to the material in the grinding chart i, the lens 2 is outside the dotted line), so that the first and second lens 2 can be respectively adapted to the external grip requirement condition: The first and second lens pads 2 can be glued into one body, and the glueing operation needs to be performed. Then, in order to make the optical axes of the first and second lens disks 2 concentrically aligned, the core adjustment operation is required, so this is The method is not only complicated, but also increases the manufacturing cost. 2. The composite mirror 4 must be bonded to the first and second lenses 1 and 2 by the adhesive layer 3, however, 'because the material of the adhesive layer 3 is usually a polymer material, unlike the first one, The glass material of the second lens 2, therefore, the optical property of the adhesive layer 3 is different from the first and second lens 2, for example, the adhesive layer 3 usually has a larger than the first and second lenses 2' The lower refractive index and higher reflectivity, absorptivity, and thus, due to the influence of the heterogeneous rubber layer 3, the composite lens m does not produce a good chromatic aberration compensation effect. Because the polymer material of the adhesive layer 3 is different from the glass material of the first and second lenses 1 and 2, the adhesive layer 3 is extremely easy to use compared to the first and second lenses 12, 201006770. Deterioration problems occur in the process without durability. 4. Since the polymer material of the adhesive layer 3 is different from the glass material of the first and second lenses 1 and 2, the thermal expansion coefficient between the adhesive layer 3 and the first and second lenses i and 2 generally has Considerable difference, the adhesive layer 3 is easily affected by thermal expansion during use, and the problem of peeling occurs. [Invention] Therefore, one of the objects of the present invention is to provide a color difference compensation effect. A one-piece glass molded composite lens that is durable and difficult to peel off. Another object of the present invention is to provide a method of manufacturing a one-piece glass mold composite lens which is simplified in process and can reduce manufacturing costs. The glass molded composite lens of the present invention comprises a first sheet and a plurality of second optical elements. The first sheet is made of a first glass nitrate material, the first glass nitrate material has a glass transition temperature, the first sheet body has a top surface, a bottom surface, and a plurality of cutting directions are formed on the top, A first optical element arranged in an array between the bottom surfaces, the first optical elements each having a first joint surface. The second optical elements are respectively made of a plurality of second glass nitrate materials, each of the second broken glass materials has a forming temperature not greater than the glass transition temperature, and the second optical elements respectively have the same Waiting for the second joint face on the first joint face. The method for manufacturing a one-piece glass mold composite lens of the present invention comprises: (A) forming a -first glass nitrate material into a "first" sheet, the first glass nitrate material having a glass transition temperature, the first sheet having a The top surface, the bottom surface, 7 201006770 and the number of edge cutting directions are formed between the top and bottom surfaces and are arranged in an array of first optical elements, each of the first optical elements having a first joint surface. (B) synchronously forming a plurality of second glass nitrate materials on the first joint surface of the first optical elements into a plurality of second optical elements, each of the second glass nitrate materials having a forming temperature not greater than the glass transition temperature, The second optical elements each have a second engaging surface that is fused to the first engaging faces.

After the cold portion, the third mold unit 70 ❹ - mirror: two second mold units I, the whole sheet Multi-chip:: fetch: 7 take out; then, when the whole-piece composite mirror L is to be cut: ': first use -uv_° to composite the whole piece::_ adhesively fixed on a cutting machine (not shown) - The computer controls the workbench fan, and then, using the CCD lens 5〇〇, shoots the alignment mark §14 and adjusts the table 3〇〇 so that each pair of positive marks μ is on the screen. For a pair of positive marks 51A of the CCD lens, when the whole-type composite lens 1GG is aligned, the operator can use the computer to control the cutting tool and make the cutting tool 7(8) along the same. The cutting direction X, Y cuts the scribe lines between the first optical elements 13, and the first optical elements 13 are precisely cut and separated, thereby cutting out a plurality of unit composite lenses 200, and thereafter, using υν light irradiation The unit composite lens 200 can make the cut UV tape 400 lose its viscosity, and thus, The composite lens 200 can be removed for subsequent assembly operations. 12 201006770 Thereby, as shown in FIG. 9, the unit composite lens 200 having the chromatic aberration compensation effect can be manufactured by the manufacturing method of the present invention. The above description can further summarize the advantages of the present invention. The top and bottom surfaces η of the first sheet 1〇 formed by the present invention are respectively formed with alignment marks for alignment. , i5, therefore, the whole-piece composite mirror # (10) can be accurately (four) after the alignment is completed, and then can effectively (4) the size accuracy of the single-tilt mirror 4 employed. The second invention is the first Forming the first optical element cuckoo, the & ^ ', , and then the first glass nitrate material 40 formed at a lower temperature in the higher temperature forming first-glass stone material 30 in the first _ 4 The second optical element 20' is formed on the first optical element 20'; since the wire temperature of the second glass nitrate material 4q is lower than the breaking temperature of the first glassy material 30, therefore, When the first-first element 20 is press-formed, not only the earlier forms are formed - The optical element 13 has no problem of deformation at all, and the second joint surface portion 21 of the second optical element 20 can more completely correspond to the surface shape of the first joint surface portion 131 of the first optical element 13 and is fused to On the first-joining surface portion 131, the composite lens 100 is caused by the first sheet body 1Q and the second glass nitrate material 4 being synchronized in the second and third mold units 6〇, 7〇. The same, the optical axis of the first and second optical elements 13, 20 will naturally be concentrically aligned without any adjustment of the core. Thus: comparison: the manufacturing method of the conventional composite lens 4, this The manufacturing method of the invention does not require the sizing operation and the adjustment operation, and only needs to be the same: By performing the core-setting operation once in the lens period, the uniform lens 2〇0 can be made to meet the requirements of the outer diameter requirement, and thus it can be seen that the manufacturing method of the present invention 13 201006770 can effectively streamline, shorten the manufacturing process, and reduce the manufacturing cost. 3. The second bonding surface portion 21 of the second optical component 20 of the present invention is directly fused to the first bonding surface i3i of the first optical component 13, so that it can be assisted by any adhesive substance. The first and second joining faces 131, 21 can be formed into a completely corresponding face shape. Therefore, the unit compound produced by the present invention is compared with the conventional composite lens 4. Lens 2〇〇 produces good chromatic aberration compensation. The second joint surface portion 21 of the second optical element 20 of the present invention is _ directly fused to the first joint surface portion i3i of the first optical elements 13, so that the present invention is compared to the conventional composite lens 4 The manufacturing method not only can effectively improve the bonding strength and stability between the second optical elements 13, 2G, but also the unit composite lens 2 manufactured by the invention is more completely free of the deterioration of the conventional adhesive layer. Problem with good durability. 5. There is no heterogeneous adhesive layer between the first and second optical elements 13 and 20 of the present invention. Therefore, the first and second optical elements 13 and 20 are not easily affected by thermal expansion. The problem of peeling off each other, 如此, after the first and second optical elements 13 and 2 are cut into the single-position composite lenses 200, the unit composite lenses can be directly annealed and set. Core, ink and other processing operations. In summary, the whole-glass mold-molded composite lens of the present invention and the manufacturing method thereof can not only produce a composite lens with high precision, good chromatic aberration compensation effect, good durability and easy peeling, but also simplify the manufacturing process and reduce the manufacturing cost. 'The choice can actually achieve the purpose of the invention. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is limited to the extent of the present invention, that is, the simple equivalent change made by the scope of the invention and the description of the invention. And modifications are still within the scope of the invention patent.
