FIELD: optical instrumentation engineering, infra-red imaging and television facilities. SUBSTANCE: the optical system uses afocal adapter 1, mirror polyhydral drum 2 in the form of a pyramid with faces 3 and axis of rotation 4, flat mirror 5 located near entrance pupil 6 of objective lens 7 of receiver 8. Optical axes 10 and 11 of adapter 1 and objective lens 7 are positioned in the same plane at an angle to each other with intersection in center 9 of objective lens entrance pupil 6. EFFECT: improved design. 2 dwg
