Optical properties of a system consisting of a mirror and a grating.
The optical properties have been studied analytically for a system consisting of a mirror and a grating, without imposing much restrictions on the manner of arranging the optical elements. For the sake of simplicity calculations were limited only to rays in the meridional plane of the system. Analytical expressions are given for the focal condition and a coma-type aberration. Remedies are described for eliminating the coma-type aberration at one wavelength, of designer's choice, without use of any auxiliary optics.
