FIELD: optoelectronic engineering and is intended for observation at low-level illuminance. SUBSTANCE: device uses a cadadioptric lens for construction of image on the photocathode of the optoelectron device, an additional optical system is introduced, which consists of a lens, turning-over system, projection mirrors installed in such a way that optical radiation passing through the peripheral zone of the cadadioptric lens would pass through the additional lens, turning-over system and would get in the eye-piece. Besides, the radiation forming lens and the pulsed laser semiconductor radiator are installed in the axis of the cadadioptric lens before its faceplate in the dead zone. EFFECT: observation in the day-time and night-time channels, reduced dimensions of the optical inlet. |
