Abstract

This paper outlines how ray trace techniques can be used to predetermine new configurations of monochromator and spectrograph gratings. Examples of Rowland Circle aberrations vs. aberration corrected configurations are given in which it has been seen that astigmatism can sometimes be reduced by over a factor of 10. When non-Rowland Circle configurations are used, astigmatism can often be reduced to zero. This is demonstrated in a new type of grating that acts as a scanning flat field spectrograph operating at better than F3 from 600-1200nm.
