Paper Abstract

A technique to measure the efficiency of diffraction gratings in the vacuum ultraviolet spectral region at any angle of incidence has been developed and will be discussed briefly. The measurements show that concave gratings do not have a uniform efficiency over their surfaces, primarily because of the change in blaze angle across the surface. Examples will be shown of results obtained using both conventionally ruled, and holographically recorded, gratings. A short discussion of stray light will be given, followed by a description of the type of contamination found in laboratory instruments and its effect on the efficiency.
