PANORAMIC SIGHT WITH BUILT-IN LASER RANGEFINDER Russian patent published in 2019 - IPC F41G3/06 G02B23/12 

FIELD: instrument engineering.

SUBSTANCE: sight can be used in optoelectronic devices of fire control systems of armored vehicles. Sight comprises head part consisting of protective glass and head mirror, visual, television, thermal imaging channels and receiving channel of laser range finder, optical axes of input pupils of which are combined into one optical axis with possibility of simultaneous operation of all four channels by means of three dichroic elements: first dichroic element reflecting visible RGB and NIR spectral ranges and transmitting MWIR, LWIR and SWIR spectral radiation bands, second dichroic element made in form of mirror plane of semi-pentaprism BU-45° an erecting visual channel system and reflecting visible RGB and transmitting NIR spectral ranges, third dichroic element reflecting SWIR and transmitting MWIR and LWIR ranges. Optical axis of the emitter of the laser range finder is parallel to the vertical axis of the sight. Before the first dichroic element there is a multi-prism optical compensator, containing small prisms AR-0°, oriented in pairs in horizontal plane.

EFFECT: reduced dimensions and compensation of image inclination for all observation channels during head mirror rotation in horizontal plane.
