Grating efficiency theory as it applies to blazed and holographic gratings

TLDR

Recently developed rigorous theories have been used to investigate the diffraction efficiency behavior of both blazed and holographic gratings. In order to assist designers of spectrometric systems, the study models blaze angles for triangular grooves and sinusoidal modulations in first and second orders, incorporating various mountings and aluminum conductivity effects. The work provides classifications of blazed and holographic gratings across the near‑UV to IR spectrum and demonstrates close agreement between theoretical predictions and experimental measurements.

Abstract

Recently developed rigorous theories have been used to investigate the diffraction efficiency behavior of both blazed and holographic gratings. In order to assist designers of spectrometric systems we have covered a complete range of blaze angles for triangular grooves and modulations for sinusoidal groove shape in first and second orders. Several types of mountings are included together with the role played by finite conductivity of aluminum. Useful classifications of both types of gratings are given, as they apply from the near uv to ir regions. Comparisons showing the close agreement between theory and experiment are presented.
