Abstract

A new concept is introduced in the theory of concave gratings: The center of the rectangular area used is not necessarily the vertex of the grating, but a point of the symmetry plane perpendicular to the grooves, lying at a varying distance w₀ from it; the additional degree of freedom thus introduced permits an improvement of focus of some mountings commonly used at present.
