HOLOGRAPHIC OPTICAL GRATING AND METHOD FOR OPTIMIZING MONOCHROMATOR CONFIGURATION

摘要

This invention comprises a novel apparatus for recording a holographic groove pattern on a diffraction grating blank (G). The recording apparatus is configured using newly developed groups of analytical equations. The invention further comprises the novel holographic diffraction grating (G) made with the inventive recording apparatus. The invention additionally comprises monochromators and spectrometers equipped with the inventive holographic diffraction grating (PG). Further, the invention comprises a monochromator configured to reduce aberrations using a newly developed group of analytical equations. Additionally, the invention comprises a method to reduce aberrations in monochromators and spectrometers using newly developed groups of analytical equations.
