Abstract

A compact solar spectrograph based on the Rowland grazing-incidence design has been developed that covers 200-3200 A and has no moving parts; it will record the entire spectrum within its range in a single exposure on the basis of pinhole optics. Three gratings are used and these are recorded on a single CCD focal plane detector. Methods used to minimize the effects of scattering include its suppression with coatings and optical components; a detector layout that subtracts scattered light effects, and a photocathode that discriminates against long wavelengths.
