INFRARED RADIATION RECEIVER Russian patent published in 2016 - IPC H01L27/14 

FIELD: instrument making.

SUBSTANCE: invention relates to devices for measuring power of heat radiation. Core: the receiver comprises vacuum chamber (21), on diametrically opposite side surfaces of which there are inlet optical windows (12, 13). Inside vacuum chamber (21) accommodates refrigerating chamber (20) and base platform (14) consisting of two parts (15, 16) with sensitive elements (17) and screens (18). Sensitive elements (17) and screens (18) are arranged on base platform (14) by means of thermal contact. Screens (18) are made in the form of grooves filled with non-infrared-transparent material. First part (15) of base platform (14) is optically coupled with first optical window (12), and second part (16) of base platform (14) - with second optical window (13).

EFFECT: technical result is higher sensitivity and resolution of the device due to increased density of sensitive elements (17) installation on base platform (14).
