Abstract
An optical reflector includes a substrate, an absorbing layer deposited on the substrate for absorbing light within a broad range of wavelengths, and a rugate film deposited on the absorbing layer and adapted to reflect wavelengths of light within a predetermined range. The reflector may further include a buffer layer disposed between the substrate and the absorbing layer for promoting the adhesion of the absorbing layer to the substrate.
