LIGHT FILTER

摘要

FIELD: quantum engineering. SUBSTANCE: light filter has leak-proof tray and parallel substrates. At least two prisms are fixed to transparent substrate close to each other through ribs on inner surface of each prism by their hypotenuse faces. Gap is formed between leg faces of prisms mounted on opposite substrates. Gap is filled with liquid containing laser beam absorbing centers. Liquid layer has compensating volume. EFFECT: enlarged surveillance and improved protection against high-power radiation. 1 dwg
