METHOD OF MANUFACTURING INFRARED LIGHT FILTER Russian patent published in 2008 - IPC F21V9/04

Abstract RU 2315231 C1

FIELD: light engineering.

SUBSTANCE: method comprises using activated LiF:U crystals as a material for the infrared filter and irradiating the crystals by neutrons. The irradiated crystals are exposed to air at a room temperature for 10-12 months and then are roasted in air at a temperature of 200-300°C for 0.5-1.5 hours.

EFFECT: enhanced thermal and radiation stability.
