PROTECTIVE DEVICE FOR INPUT OPTICS OF OPTICAL AND OPTICAL- ELECTRON INSTRUMENTS

摘要

FIELD: optical instrumentation. SUBSTANCE: reflective coat is deposited on face surface of reflecting element for reflection of incident external radiation in direction of source of external radiation and for provision of serviceability of optical and optical-electron instruments through the remaining transparent portion of input optics. EFFECT: increased efficiency of optical and optical-electron instruments used under combat conditions thanks to active-passive protection of their input optics. 15 cl, 3 dwg
