Paper Abstract

A combination of dielectric thin film and laser absorption dye technologies was introduced to fabricate a clear reflective aircrew's laser eye protection (LEP) visor. The interlayer and thin film layer materials for the high and low refractive indices are optimized. A clear visor with 26 % visibility was achieved for more than four optical densities (OD) LEP. In addition, an oxide compound film coating was explored to seek extra protection for the delaminating of the fragile multilayer dielectric thin film coating. As a side effect, applying surface-active agents on the oxide compound film resulted in good dustproof and anti-fog properties.
