Abstract

Verification of component specification and EUV optical performance for the diffraction gratings of the normal incidence EUV spectrograph of SOHO/CDS is discussed. This discussion includes: a comparison of experimentally obtained EUV spectral images of a point source with corresponding ray trace analysis, in-band Lyman alpha leak determination, verification of toroidal radii of curvature, verification of blaze direction by calculation and VUV measurement, and zero order efficiency at 124 nm.
