The prism installation device eliminates the stress of direct installation of the prism; the framework is improved, framework positioning is not needed, and the reliable and stable requirements of the positioning are satisfied through directly positioning prism surface; the pressure spring pieces are used for positioning, thereby ensuring accuracy of positioning; and flexible two-side pressure manner and simple point contact manner ensure the stability of positioning.
Description
Technical field
The utility model relates to optoelectronic areas and mechanical field, especially a kind of optical instrument is used the unstressed and prism erecting device that is easy to dismantle.
Background technology
The installation of prism is one of major issue in optical instrument and the Experiments of Optics.In general, prism is installed the following condition that is subject to: the installation requirement of the inplace stability of the position of related features size of the light path of optical instrument or Experiments of Optics, prism size and shape, admissible prism surface, admissible erection stress, each surperficial shock resistance of prism, long-term installation, the deformation that admissible temperature is brought and stress, special cemented prism etc. in addition, because need to clean behind the dust fall of lens optical surface under the conventional environment, perhaps same position need be changed different prisms but will guarantee its repetitive positioning accuracy etc. in Experiments of Optics.Therefore prism is installed usually more complicated more difficult than common lens.
Experiments of Optics are in the market debugged the prism erecting frame of usefulness generally by base, column, and the prism platform, stage clip or briquetting are formed.Prism directly is placed on the platform, by pressing plate and stage clip prism is applied fastening force and fix.Its structure is simple relatively, and prism only is placed on the platform, has no bearing accuracy and can say; Only depend on the fixed form inplace stability of stage clip relatively poor, repetitive positioning accuracy is low, the situation of difficult that resets behind the prism can occur touching accidentally; Because stage clip or briquetting directly are pressed on the prism, make prism produce distortion simultaneously, in the high-precision optical experiment, can't meet the demands.The prism location instability that the prism erecting bed that has has avoided stage clip to cause, the mode of employing screw in compression has but been aggravated the excessive defective that causes the prism distortion of stress.
Prism in the optical instrument is installed generally at using design.Can be divided into built-in and half built-in installation.Built-in installation refers to that prism is positioned at instrument internal, install to need not to change, adjust or clean, therefore no longer dismounting, in case but prism install and error takes place will be difficult to remedy; Though partly the built-in prism that then refers to is installed in the instrument in the ordinary course of things,, when design, just need the consideration prism to be convenient to dismounting because the needs of replacing, adjustment or cleaning are arranged; But it is reliable to require prism to install during instrument work simultaneously, position stability.
Main prism mounting means in the present optical instrument comprises gluing, pressing plate, stage clip, pressure ring etc.Adhesive means directly adheres to prism surface, causes prism to dismantle.Even remove by force, prism also is easy to stained even damaged.Pressing plate, stage clip and pressure ring mode all have the aforesaid stresses problem.Generally, take into account unstressed, position stability, the prism mounting means that is easy to disassembly, cleaning is comparatively rare.
The utility model content
The purpose of this utility model provides that a kind of optical instrument uses the unstressed and prism erecting device that is easy to dismantle, low to solve the bearing accuracy that occurs in the prism installation process in the conventional art, poor stability, it is unreliable to install, and is not easy problems such as dismounting.
In order to achieve the above object, the technical scheme that the utility model adopted is:
Optical instrument is used the unstressed and prism erecting device that is easy to dismantle includes prism, and base is characterized in that: be fixed with the left and right side bolt block on the described base, screwed togather bolt respectively on the described left and right side bolt block; Be placed with the prism framework between the left and right side bolt block, described prism framework is made up of left and right side frame and the bolt that connects left and right side frame, and described prism is sandwiched between the left and right side frame; Be provided with pressing plate between described left and right side frame and the corresponding left and right side bolt block, bolt on the described left and right side bolt block withstands on respectively on the side of corresponding pressing plate, described pressing plate has several salient points on the another side, and described salient point withstands on described left and right side frame lateral surface; The rear of described left and right side bolt block is fixed with the stage clip post respectively, on the described stage clip post making leaf spring is installed, and is pressed on the and arranged on left and right sides of prism frame frame under the described making leaf spring.
Described optical instrument is used the unstressed and prism erecting device that is easy to dismantle, it is characterized in that: described prism is a rectangular prism.
Described optical instrument is used the unstressed and prism erecting device that is easy to dismantle is characterized in that: fit between the lower surface of described prism and the described base.
Described optical instrument is used the unstressed and prism erecting device that is easy to dismantle, it is characterized in that: described prism is a right-angle prism, there is light hole base and joint place, prism lower surface.
The utility model has adopted the prism framework, has eliminated the stress that prism is directly installed; By improvement, avoided simultaneously, but, satisfied the reliable and stability requirement of location directly with the prism surface location with the framework location to framework; Adopt making leaf spring to carry out location positioning, can guarantee bearing accuracy; At last, the method that contacts with single-point of two side compression modes has guaranteed the stability of location flexibly.
