Paper Abstract

Holographic diffraction gratings, when used in a spectroscopic application, produce excellent image quality and stray-light rejection, but sometimes lack optimum efficiency. Ionetching through a sinusoidal photoresist groove into a glass substrate can produce triangular profiles comparable with the groove shape produced by classical diamond burnishing. This can be accomplished in both plano, spherical and aspheric substrates to produce gratings comparable in efficiency to classically ruled gratings.
