<title>Aberration-corrected holographic concave diffraction grating with high spectral resolution</title>

Abstract

The design, production, and evaluation of a polychromator with high spectral resolution are discussed. In the example of using it in environmental monitoring some aspects of the designing process are shown. Some useful tools, such as spot diagrams and lineprofiles, to evaluate the performance of a grating are shown. As a part of this designing process the use of surface contouring is discussed. Some results of the performance are presented.
