The utility model content
Technical problem to be solved in the utility model is: a kind of optical system of light riflescope is provided, under the prerequisite that guarantees optical quality, has reduced objective lens eyeglass quantity, reduced the weight and the cost of whole system.
For solving the problems of the technologies described above, the technical solution of the utility model is: the optical system of light riflescope, arrive the picture side direction along the thing side, comprise the objective lens, image rotation lenses group and the eyepiece group that are arranged in order setting, described objective lens comprises a plastic aspherical element eyeglass, and described plastic aspherical element eyeglass comprises an aspheric surface and a diffraction surfaces.
As a kind of optimized technical scheme, to the picture side direction, first face of described plastic aspherical element eyeglass is an aspheric surface along the thing side, and second face is diffraction surfaces.
As another kind of optimized technical scheme, to the picture side direction, first face of described plastic aspherical element eyeglass is a diffraction surfaces along the thing side, and second face is aspheric surface.
As a kind of optimized technical scheme, described objective lens also comprises a glass lens sheet, and to the picture side direction, described plastic aspherical element eyeglass and described glass lens sheet are arranged in order along the thing side.
As a kind of optimized technical scheme, the outer surface of described plastic aspherical element eyeglass has the plated film layer.
After having adopted technique scheme, the beneficial effects of the utility model are:
1. in the utility model, objective lens comprises a plastic aspherical element eyeglass, and described plastic aspherical element eyeglass comprises an aspheric surface and a diffraction surfaces.Described objective lens can also comprise a glass lens sheet that is used to focus, and to the picture side direction, described plastic aspherical element eyeglass and described glass lens sheet are arranged in order along the thing side.The utility model can utilize aspheric surface, diffraction surfaces and the glass lens sheet of plastic aspherical element eyeglass to come aberration correction, substitutes traditional sighting telescope optical system and utilizes the incompatible aberration correction of some set of lenses; The utility model utilizes the diffraction surfaces of aspherical lens to come correcting chromatic aberration, substitutes traditional sighting telescope optical system and utilizes the cemented doublet of the lens composition of some different abbe numbers to come correcting chromatic aberration, has guaranteed excellent optical performance.
2. the utility model adopts two eyeglasses to replace the objective lens rifle of three of tradition or four eyeglass compositions to take aim at system, the weight and the cost of system have been reduced, in addition, can adopt injection molding process to produce the plastic aspherical element eyeglass, not only reduced foozle, promote the product optical property, and simplified the eyeglass production procedure, also can reduce the eyeglass cost.
3. the utility model has the plated film layer at the outer surface of plastic aspherical element eyeglass, improved the adaptive capacity to environment of glass lens, satisfy the environment for use needs of gun sight fully, avoided because environmental factor reduces the imaging performance of gun sight such as influences such as temperature, humidity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the optical system diagram of the utility model embodiment.
Among the figure: 1. objective lens, 11. plastic aspherical element eyeglasses, 12. glass lens sheets, 2. image rotation lenses group, 3. eyepiece group, A. aspheric surface, B. diffraction surfaces.
The specific embodiment
As shown in drawings, a kind of optical system of light riflescope.Present embodiment is the situation that the utility model is applied to the 3-12x50SF riflescope.
To the picture side direction, this optical system comprises objective lens 1, image rotation lenses group 2 and the eyepiece group 3 that is arranged in order setting along the thing side.
Described objective lens 1 comprises a plastic aspherical element eyeglass 11, and described plastic aspherical element eyeglass 11 comprises an aspheric surface and a diffraction surfaces.Described objective lens can also comprise a glass lens sheet 12, and to the picture side direction, described plastic aspherical element eyeglass 11 and described glass lens sheet 12 are arranged in order along the thing side.What glass lens sheet 12 adopted is the plano-concave simple lens.Image rotation lenses group 2 and eyepiece group 3 are existing known technology, and present embodiment is no longer done specific descriptions.
In the present embodiment, to the picture side direction, first face of described plastic aspherical element eyeglass 11 is aspheric surface A along the thing side, and second face is diffraction surfaces B.Because the position of aspheric surface and diffraction surfaces can exchange, therefore, to the picture side direction, also can be: first face of plastic aspherical element eyeglass 11 be a diffraction surfaces along the thing side, and second face is aspheric surface.
Because used eyeglass in the general camera lens, can regard the part of spheroid as, its surface curvature is fixed, and optically inevitably has certain defects of vision, produces spherical aberration.Aspherical mirror develops for correcting spherical aberration, aspheric surface refers to quadratic surfaces such as ellipsoid, parabola, hyperboloid and high order curved surface more, aspherical lens can allow paraxial rays overlap aberration correction with the formed focal position of axial ray far away by revising the curvature of lens surface.And diffraction surfaces is to produce diffraction grating at lens surface, utilizes many seam diffraction and interference effect, and the light beam that is mapped on the grating is carried out chromatic dispersion by the difference of wavelength, focuses on and formation spectrum through the imaging mirror again, has the function of good correcting chromatic aberration.
Therefore, the utility model can utilize aspheric surface A, diffraction surfaces B and the glass lens sheet 12 of plastic aspherical element eyeglass to come aberration correction, substitutes traditional sighting telescope optical system and utilizes the incompatible aberration correction of some set of lenses; Utilize the diffraction surfaces B of aspherical lens 11 to come correcting chromatic aberration, substitute traditional sighting telescope optical system and utilize the cemented doublet of the lens composition of some different abbe numbers to come correcting chromatic aberration, guaranteed excellent optical performance.
The aspheric surface A of plastic aspherical element eyeglass 11 and diffraction surfaces B are once molding formed by two moulds respectively, have reduced foozle like this, have promoted the product optical property.The manufacture process of the balsaming lens in the tradition sighting telescope optical system objective lens is a relative complex, yet relatively, plastic aspherical element lens 11 in the utility model are plastic materials, can produce in enormous quantities by injection mo(u)lding, and injection molding process is fairly simple, and manufacturing cost also can be reduced by production in enormous quantities.
In addition, as required, can be at the outer surface plated film of plastic aspherical element eyeglass 11, make it have the plated film layer, the plated film layer specifically can be hard membrane layer or town's moisture film, in order to improve the adaptive capacity to environment of glass lens, satisfy the environment for use needs of gun sight, avoided because environmental factor reduces the imaging performance of gun sight such as influences such as temperature, humidity.
The foregoing description only is giving an example of the utility model specific embodiment; protection domain of the present utility model is as the criterion with the content of claim; any equivalent transformation that carries out based on technology enlightenment of the present utility model is all within protection domain of the present utility model.
