Photometric Evaluation of Reflection-Reducing Coating for Aircraft Instrument Cover Glass

摘要

Comparisons were made between plain instrument cover glass used on aircraft instrument panels and cover glass deposited with multilayer antireflection coating conforming to MIL-C-14806 and AMS 2521. Photometric measurements of reflections, light transmission and contrast indicated the effectiveness of the reflection-reducing coating. Reflected glare from the face of instruments was significantly reduced by the reflection-reducing coating and increased light transmission enhanced contrast on instrument dial faces. (Author)
