Paper Abstract

The development of interferographic techniques has led to an improvement in the quality of gratings available for spectroscopy and has permitted the manufacture of entirely new types of gratings. Unfortunately different aspects of performance have frequently been studied in isolation and it is not always appreciated that they are interrelated. A dramatic improvement in say, the focal properties may be at the expense of reduced efficiency or dispersion. The relative importance of these factors and the extent of any overall improvement will depend strongly upon the design of the instrument and the purpose for which it is built. The purpose of the present paper is to review the contribution of interference grating technology to spectroscopy in the whole of the ultraviolet region. Special emphasis will be given to the properties of blazed gratings both made in photoresist and ion etched into the substrate. Plane and concave gratings may be made with blaze wavelengths between 300 nm and 3 nm. The efficiency is generally equal or superior to those of ruled gratings and this can sometimes, but not always, be combined with good holographic correction of aberrations.
