Abstract

Calculations are presented for a set of aberration-corrected holographic concave gratings for possible use in space mission instruments. It is concluded that, for the visible range 0.26–1.02 μm when detectors with a 15-μm pixel size are used, a total field of view of 1° is possible at an aperture of f/7.0. For the infrared regions 0.9–2.5 μm and 2.4–4.2 μm, in which detector arrays have larger pixel sizes of 30–40 μm, a spatial field of view of 2° at f/7.0 and, 1.0° at f/3.5 can be achieved. An exploration of spectrum lengths showed that performance starts to fall off sharply for lengths over 15 mm at a focal length of 150 mm (i.e., a spectral angular extent of 6°).
