Abstract
The utility model discloses a prism riflescope optical system free of division line swing parallax. The prism riflescope optical system comprises an objective lens, a prism group and an eye lens group which are sequentially arranged from an object space. The prism group is formed by a ridge prism and a coincidence prism, the coincidence prism is formed by gluing of a half pentaprism and a wedge-shaped prism, the wedge-shaped prism is located above the half pentaprism, the top surface of the wedge-shaped prism is provided with a division line pattern, light at the center of the division line pattern and a primary optical axis are intersected on an object space focus of the eye lens group, and the light is perpendicular to the plane where a division line is located. According to the prism riflescope optical system, the half pentaprism and the wedge-shaped prism are glued to form the coincidence prism on the basis of a traditional telescope system, the division line is drawn on the top surface of the wedge-shaped prism, so that the division line is perpendicular to the optical axis, the problem that a reticle generates the swing parallax is solved, and higher accuracy can be achieved when users use a riflescope for aiming.
Description
Technical field
The utility model relates to prismatic telescope optical system, especially swings parallax prism rifle without division line and takes aim at optical system.
Background technology
As shown in Figure 1, for traditional prism rifle is taken aim at, mainly formed by object lens 10, prism group 20, eyepiece group 30, its division line pattern is engraved on the face 201 of prism, but because the face 201 of prism cannot be vertical with the optical axis in system, so in the time that eyepiece is observed, division line meeting along with eyes up and down or move left and right and produce swing, produced thus the parallax of division line and object observing.
Utility model content
For solving the problems of the technologies described above, the object that the utility model is wanted is to provide one and takes aim at optical system without division line swing parallax prism rifle.
The technical solution adopted in the utility model is:
A kind of swing parallax prism rifle without division line and take aim at optical system, comprise being arranged in order from object space: object lens, a prism group, an eyepiece group; Described prism group is made up of roof prism and coincidence prism; Described roof prism is vertical with primary optical axis towards the one side of object lens, and the opposite face of described roof prism and coincidence prism is parallel to each other; Described coincidence prism is formed by half pentaprism and wedge-shaped mirrors gummed, and wedge-shaped mirrors is positioned on half pentaprism; The end face of described wedge-shaped mirrors is provided with division line pattern, and the light of division line pattern center meets at the object focus of eyepiece group by coincidence prism and primary optical axis, and this light is vertical with division line place face.
As the further improvement of the technical program, between described object lens and prism group, be provided with an object lens additional mirror.
Wherein, described eyepiece group comprises by object space and works the eyepiece negative lens, eyepiece positive lens, the eyepiece monolithic that are arranged in order.
The cemented surface of described half pentaprism and wedge-shaped mirrors is coated with spectro-film.
Described object lens are cemented objective.
The beneficial effects of the utility model:
The utility model prism rifle is taken aim at optical system taking traditional telescopic system as basis, use two prism cementings of half pentaprism and wedge-shaped mirrors to become coincidence prism, division line is portrayed on the end face of wedge-shaped mirrors, division line is just vertical with optical axis like this, solution graticle produces the defect that swings parallax, and allowing user take aim at the work aiming used time at this rifle of use can be more accurate.
Brief description of the drawings
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Fig. 1 is the structure chart that conventional prism rifle is taken aim at optical system;
Fig. 2 is the structure chart that the utility model prism rifle is taken aim at optical system.
Detailed description of the invention
Shown in figure Fig. 2, swing parallax prism rifle without division line and take aim at optical system for of the present utility model, comprise being arranged in order from object space: object lens 10, an object lens additional mirror 90, a prism group 20, an eyepiece group 30; Described prism group 20 is made up of roof prism 40 and coincidence prism 50; Described roof prism 40 is vertical with primary optical axis 60 towards the one side of object lens 10, and described roof prism 40 is parallel to each other with the opposite face of coincidence prism 50; Described coincidence prism 50 is formed by half pentaprism 70 and wedge-shaped mirrors 80 gummeds, and cemented surface is coated with spectro-film, and wedge-shaped mirrors 80 is positioned on half pentaprism 70; The end face of described wedge-shaped mirrors 80 is provided with division line pattern, and this end face is dividing plane 201, and the light of division line pattern center meets at the object focus f of eyepiece group by coincidence prism 50 and primary optical axis 60, and this light is vertical with dividing plane 201.
Wherein, described eyepiece group 30 comprises by object space and works the eyepiece negative lens 100, eyepiece positive lens 110, the eyepiece monolithic 120 that are arranged in order; In the technical program, described object lens 10 are cemented objective.
The utility model prism rifle is taken aim at optical system taking traditional telescopic system as basis, use 80 two prism cementings of half pentaprism 70 and wedge-shaped mirrors to become coincidence prism 50, division line is portrayed on the end face of wedge-shaped mirrors 80, division line is just vertical with optical axis like this, when this vertical relation makes us observe division line in order side, no matter eyes up and down or move left and right, division line also there will not be swing, solution graticle produces the defect that swings parallax, and allowing user take aim at the work aiming used time at this rifle of use can be more accurate.
The foregoing is only preferential embodiment of the present utility model, the utility model is not limited to above-mentioned embodiment, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
