Applications of Holographic Gratings to Two-Dimensional Spectroscopy

Kurzfassung

Calcualtions are presented for a set of aberation-corrected holographic concave gratings for possible use in space mission instruments. It is concluded that, for the visible range 0.26-1.02 muem when detectors with a 15 muem 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 muem and 2.4-4.2 muem, in which detector arrays have larger pixel sizes of 30-40 muem, 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 length of 150 mm (i.e., aspectral angular extent of 6).
