Reflecting Schmidt imaging spectrometers

A new very wide angle imaging spectrometer optical configuration which uses an all-reflecting Schmidt camera with a prism spectrometer to give a strip field of view is presented. Three complete systems (15 degrees, 8.5 degrees, 2.6 degrees FOV), including fore optics and spectrometer optics, were designed. These slit fields of view are pushbroomed across object space to create a 2-D image. The performance of each near diffraction-limited system and optical prescriptions is detailed. An all-reflecting Schmidt camera fore-optics system with a 60 degree field of view is also given.
