Book Description

The unique properties of diffraction gratings make the optical design of diffraction spectrometers a complex problem. This Spotlight connects optical design and diffraction grating fabrication to address issues of diffraction efficiency, tolerance analysis, and optimization techniques. It further explores performance testing of gratings and modification of classical spectrometers using modern design and fabrication techniques.

Preface

Ray tracing and optimization programs - developed simultaneously with diffraction grating fabrication technology - were originally focused on lens design. New features, such as mirror systems and diffraction spectrometer designs, were gradually added, but the developers were not always familiar with all of the specific features and limitations of the technology. This Spotlight connects optical design and diffraction grating fabrication, focusing mainly on surface relief reflection gratings for spectroscopy.
