Abstract
The invention relates to a CaF2 lens clamping device which comprises a lens barrel, and a first snap ring and a second snap ring arranged on both ends of the lens barrel; the radius of the inner side surface of the first snap ring is the same with the optical radius of a CaF2 lens; when the clamping device of the invention clamps the lens, no slot needs to be arranged on the lens, thereby reducing the production cost of the CaF2 lens, reducing the clamping stress produced between the snap rings and the CaF2 lens when in clamping, greatly reducing the alignment stress of the CaF2 lens, facilitating cooling, scattering the paste stress of glue to the CaF2 lens and well protecting the CaF2 lens, so that a component is adaptive to special use environment and the processing cost is lower.
Description
Technical field
The present invention relates to a kind of CaF
2Lens clamping device and method thereof.
Background technology
CaF
2Camera lens has been widely used in the infrared field, because this material mechanical processing characteristics is relatively poor, makes that the lens cost made from this material is higher, and at present usually the method for clamping of the fluting of employing be difficult to make CaF
2Lens satisfy special environment for use.
Summary of the invention
In order to solve the technical matters described in the background technology, the invention provides a kind of CaF
2Lens clamping device and method thereof can be good at guaranteeing the image quality of lens.
Technical solution of the present invention is: the present invention is a kind of CaF
2Lens clamping device, its special character is: this device comprises lens barrel, is arranged on first trim ring and second trim ring at lens barrel two ends; The radius of the described first trim ring medial surface and CaF
2The optics radius of lens is identical.
Above-mentioned clamping device also comprises rubber sheet gasket, and described rubber sheet gasket is arranged on the medial surface of second trim ring.
The hole for injecting glue that has symmetry in the radial direction of above-mentioned lens barrel.
The first above-mentioned trim ring and the outside surface of second trim ring are provided with screw thread.
A kind of CaF
2The clamp method of lens, its special character are that this method may further comprise the steps:
1) processing of trim ring:
1.1) at first by mechanical rough machined mode, make the radius of the surface of contact that contacts with lens on the trim ring of winning close to the optics radius of lens;
1.2) then, on the optics processing platform, utilize testplate, make the radius of surface of contact of roughwrought first trim ring equal the optics radius of lens;
2) require to debug according to optical design:
2.1) at first the first trim ring band glue and lens barrel are fixed;
2.2) be datum clamp face with this first trim ring secondly, with CaF
2Lens are packed in the lens barrel;
2.3) in the lens barrel of then rubber gasket, second trim ring being packed into successively, the last a few circle screw thread place's point glue on second trim ring;
2.4) check this CaF
2The stress situation of lens, corresponding CaF on lens barrel
2The hole for injecting glue place injecting glue of lens.
The present invention has the following advantages:
1, adopt clamping device of the present invention and clamp method that lens are carried out clamping, lens do not need to slot, and have reduced CaF
2The production cost of lens;
2, adopt clamping device of the present invention and clamp method lens to be carried out clamping, trim ring and CaF
2Contact between the lens is the face contact, trim ring and CaF in the time of can reducing clamping
2The nip stress that produces between the lens;
3, adopt clamping device of the present invention and clamp method lens to be carried out clamping, trim ring and CaF
2Surface of contact between the lens is bigger, is conducive to dispel the heat, and has avoided in the processing in later stage, because amount of localized heat is big, destroys CaF
2Lens;
4, adopt clamping device of the present invention and clamp method that lens are carried out clamping, the processing cost of trim ring is lower, and lens barrel directly is processed into the face of radius, and processing cost is higher;
5, adopt clamping device of the present invention and clamp method lens to be carried out clamping, first trim ring and CaF
2Rubber gasket is arranged between the eyeglass, can reduce CaF greatly
2Lens debug stress, well to CaF
2Lens are protected, and make this assembly adapt to special environment for use;
6, adopt clamping device of the present invention and clamp method that lens are carried out clamping because the hole for injecting glue that has symmetry in the radial direction of lens barrel, can dispersion agent to CaF
2The stickup stress of lens is simultaneously with CaF
2Lens well are fixed in the lens barrel.
Description of drawings
Fig. 1 is the synoptic diagram that CaF2 lens clamping device of the present invention is installed convex lens;
Fig. 2 is CaF of the present invention
2Lens clamping device is installed the synoptic diagram of concavees lens.
Embodiment
Referring to Fig. 1,2, CaF of the present invention
2Lens clamping device comprises lens barrel 1, is arranged on first trim ring 2 and second trim ring 3 of lens barrel 1 rear and front end; Radius and the CaF of first trim ring, 2 medial surfaces
2The optics radius of lens 4 is identical; First trim ring 2, second trim ring 3 are arranged on the radial line both sides of lens barrel 1, leave therebetween CaF is installed
2The space of lens 4, wherein, CaF
2Lens 4 can be that convex lens also can be concavees lens.
In order to reduce this device greatly to CaF
2Lens debug stress, well to CaF
2Lens are protected, and make this device adapt to special environment for use, also are provided with rubber sheet gasket 5 in the device, and this rubber sheet gasket 5 is arranged on the medial surface of second trim ring 3.
Simultaneously, for dispersion agent to CaF
