Embodiment Construction

[0023] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] A compact wide-field-of-view white light sight optical system of this embodiment adopts a Keplerian telescopic system, including an objective lens group, a relay image group, a reticle and an eyepiece group. The object to be measured generates an inverted image through the objective lens group, and is imaged on the reticle after the image transfer group, and the inverted image formed by the objective lens is erected, and finally reaches the human eye through the eyepiece group. The distance between the objective lens group and the relay group is 48.3mm, the distance between the relay group and the reticle is 24.84mm, and the distance between the reticle and the eyepiece group is 7.9mm.

[0025] Such as figure 1 As shown, the objective lens group adopts 2 groups of 3 spherical lenses, including the first lens group 1 ...

Abstract

The invention discloses a compact wide-field white light sighting telescope optical system, which adopts a Kepler telescope system and comprises an objective lens group, an image rotation group, a reticle and an eyepiece group, the objective lens group adopts two groups of three-piece spherical lenses, the image rotation group adopts three groups of five-piece spherical lenses, and the image rotation group is arranged behind an image plane of the objective lens group; the reticle is arranged behind the image rotation group, and the eyepiece group adopts three groups of five spherical lenses and comprises a first eyepiece lens group, a second eyepiece lens group and a third eyepiece lens group. The white light sighting telescope optical system is good in imaging quality, free of sensitive size, good in lens processing technology, reasonable in optical element arrangement, compact in structure, small in size and high in engineering realizability, and has practical application value.

Description

technical field [0001] The invention belongs to the technical field of optical instruments, and specifically relates to a compact wide-field-of-view white light sight optical system, which can improve man-machine efficiency, effectively reduce system weight, and help improve shooting accuracy. shooting etc. Background technique [0002] Most of the existing white light sights have long structural dimensions, relatively heavy weight, and relatively complex structures, which cannot meet the requirements of wide field of view, light weight, compact system, and salt spray environment at the same time, resulting in the compatibility of some light weapon platforms. Poor. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a compact wide-field-of-view white light sight optical system. On the premise of ensuring comprehensive image quality, the transmittance and anti-corrosion performance of the system are improved, the weight...
