Description

A gun sight that presents two images with different magnifications in the same field of view

technical field

The utility model relates to a gun sight which presents two images with different magnifications in the same field of view.

Background technique

At present, sights are mainly divided into three categories: telescopic sights, collimating sights, and reflective sights. Among them, telescopic sights have the function of magnification and can see and identify distant targets. For long-distance precise shooting, its basic structure is composed of objective lens group, inverted image group and eyepiece group, plus a reticle. However, if the user's position must be fixed at a certain place, and the shooting target is too far away and the imaging is relatively small, the shooting accuracy will not be guaranteed, or the shooting target is too close, When the imaging is relatively large, it is not conducive to finding and finding the target. Therefore, some existing manufacturers have designed adjustable magnification scopes. The slow speed leads to the loss of the target, which brings some inconvenience to the user.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a gun sight that can quickly aim and shoot in the same field of view and present two images of different magnifications without adjusting the field of view.

The technical solution adopted by the utility model is: the utility model comprises a housing, two groups of first optical systems and second optical systems with different magnifications arranged in the housing, the first optical system and the second Images with different magnifications by the optical system can be simultaneously presented in the same field of view.

The first optical system includes an objective lens group, a rectangular prism group, a dividing mechanism, a first inverted image group, and an eyepiece group arranged in the housing from front to back, and the second optical system includes the objective lens group, The rectangular prism group, the dividing mechanism, the second inverted image group, the eyepiece group, and the first reflective mirror group obliquely arranged below the rectangular prism group are opposite to the first reflective mirror group and A second reflective mirror group with an opposite inclination direction, a third reflective mirror group opposite to the second reflector group and with an opposite inclination direction, and a semi-transparent and semi-reflective film layer is arranged on the right-angle prism group.

The gun sight also includes a flat reflective reticle arranged in the housing and above the prism inverted image group, and an LED backlight located above the flat reflective reticle to provide illumination for it.

The beneficial effects of the utility model are: since the utility model includes a housing, two groups of first optical systems and second optical systems with different magnifications arranged in the housing, the first optical system and the second optical system Images with different magnifications of the system can be presented in the same field of view at the same time. At short distances, optical systems with low magnifications can be used, and optical systems with high magnifications can be used at long distances, which do not conflict with each other. Therefore, the utility model does not need Adjust the field of view and quickly aim and shoot.
