An Eye Protective Panel for Flash-Blindness Protection Using Triplet State Photochromism

Not Accessible

Your library or personal account may give you access

Abstract

A photochromic panel is described which has a viewing area of 15.0 cm × 20.0 cm and a thickness of 6.0 cm. It includes two photochromic plates of epoxy plastic containing four aromatic hydrocarbon compounds which are excited to their triplet states with two xenon flashlamps. The triplet absorption of the aromatic compounds results in a photochromic absorbance of 2.42 when the panel is activated with a 3000-J flash; 85% of the final absorbance is achieved 150 μsec after the beginning of the flash. The transmission of the panel recovers to 37% 5 sec after the panel darkens. The open-state transmission of the panel is 83%.
