A study of laser absorber IR282 in plastic and liquid media
Abstract
A PMMA Air Force visor with 1.06 micron absorber IR282 and .53 micron absorber K283 was studied for its utility as a laser protective material. The visor material was found to have an optical density approx. 6 at 1.06 micron and approx. 4 at .53 micron with a luminous transmittance of 44%. More bleaching was observed at high irradiance levels for IR282 in PMMA than in MMA. Pulse narrowing effects were noted and taken into account for the optical density calculations. An explanation is given for the shape of the transmitted pulse.
