Abstract

Holographic rejection filters for eye protection against lasers can successfully be fabricated on DCG-coated glass substrates with excellent performances such as narrow spectral bandwidth, optical densities superior to 4.5 and low noise. However, to protect the eye against shocks a more resistant substrate must be used. Since polycarbonate shows good optical qualities, it appears to be a good substitute to glass. Nevertheless, ways must be found to improve the adhesion of DCG layers onto the hydrophobic material before obtaining the same performances as those shown by filters recorded on glass substrates.
