12 December 1984 Unusual Diffraction Grating Mountings For The Vacuum Ultraviolet
Author Affiliations +
The concave grating provides both focusing and dispersion in one component, thus reducing the number of reflecting surfaces in a VUV spectroscope and thereby conserving radiation. Most concave grating spectroscopes use well known grating mountings, such as the Rowland circle, Wadsworth, Abney, etc. However, requirements imposed by spectroscopy in space and the use of synchrotron radiation have resulted in special types of mountings to accomodate the conditions peculiar to each of these two branches of research and that are not found in the usual laboratory radiation sources. Some of these special mountings are not new, having first been discovered three decades ago and since rediscovered.
