SURVEILLANCE DEVICE - SIGHT WITH BUILT-IN LASER RANGE FINDER Russian patent published in 2020 - IPC G02B23/12 F41G3/06 

FIELD: optics.

SUBSTANCE: device can be used in optoelectronic devices of fire control systems of armored vehicles. Surveillance apparatus comprises a head portion and two vertically arranged channels: visual optical variable magnification and multiple thermal imaging channels. Visual optical channel inversion system comprises three components. First component consists of negative convex-concave, negative concave-convex and biconvex lenses, the second one contains positive concave-convex lens, the third one – gluing from negative convex-concave lens facing with convexity to object, and biconvex lens. Field corrector is a positive concave-convex lens. First, second and third components of the inversion system are movable along the optical axis in two extreme positions.

EFFECT: providing perception of objects of the same value as in observation with the naked eye, by increasing the optical magnification of a single visual channel and increasing the visual field of the multiple optical visual channel.
