Abstract

The optimization of a laminar groove grating was determined by the use of electromagnetic theory. It was found that the absolute efficiency of optimized laminar and sinusoidal groove gratings are about the same, and that triangular groove gratings show higher efficiency. However, in the examples studied, laminar gratings showed considerably less second and third order contamination than the equivalently optimized triangular grooved gratings.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.
