Abstract
A high resolution XUV imaging spectrometer is designed for Japanese solar mission Solar-B. A spherical varied line-space (SVLS) grating is chosen so as to obtain high spectral and spatial resolution within the spectral range of 25 to 29 nm. The spectral image focusing properties are compared with those with toroidal uniform line-space (TULS) grating design and the SVLS design is found to be superior to the TULS design in off-plane spectral images and also in insensitiveness to optical misalignment.
