COLLIMATOR THERMAL-VISION SIGHT Russian patent published in 2019 - IPC F41G1/00 

FIELD: optics.

SUBSTANCE: invention relates to optical instrument-making and can be used in optical collimator sights. Collimator thermal-vision sight comprises a collimator channel in the visible range of spectrum and for simultaneous observation in two spectral ranges it also comprises infrared lens (1) in one housing and a photodetector in the form of an array of microbolometers in the focal plane of lens (2) with a sensitivity area of not less than 0.8 and not more than 17 mcm, signal processing unit and formation of an electronic aiming mark; and also a matrix display with a resolution of at least 324*256 pixels. Wherein the optical axis of the collimator channel and display are parallel with a deviation of no more than 15 degrees.

EFFECT: provided is convenience of combining a collimator sight and a thermal-vision sight without the need for precise positioning of an observer's eye with respect to the optical axis, ability to observe with two eyes from any position and at distance from the sight, which together with the proposed indicators of the lens sensitivity and the resolution of the matrix display increases the detectability when observing and conducting aimed shooting, not only in the visible range of electromagnetic radiation, but also in the spectral range of the near and far infrared spectrum, invisible to the naked eye.
