IR Laser Radiation Eye Protector.
Abstract
Eye protection equipment has been developed that makes possible safe, unobstructed viewing in environments of potential damage caused by infrared laser radiation. The viewing window consists of a 3-mm water sheet contained within Lucite panes. The water absorbs virtually all the radiation at all wavelengths in the IR greater than 1.9 micrometers. A 3-micrometers laser beam from a continuous HF laser at a power level of 15 W and a heat flux of 400 W/sq. cm. for 20 sec. produced a depression in the beamward Lucite window pane, but did not penetrate to the water.
