Abstract: A monochromator of the Czerny-Turner type includes an entrance slit, a collimating mirror for receiving light output by the entrance slit, a planar grating for receiving light reflected by the collimating mirror, a focusing mirror for receiving light reflected by the grating, and an exit slit for receiving light focused by the focusing mirror. Light generally proceeds from the entrance slit to the collimating mirror, form the collimating mirror to the grating, from the grating to the focusing mirror and from the focusing mirror to the exit slit. The improvement comprises the use of a single toroidal collimating mirror in the system in combination with a spherical focusing mirror.

Abstract: A modified concentric spectrograph for diffracting light with high stray light rejection without astigmatism is provided. The modified spectrograph includes a grating, a lens, and at least one entrance port and one exit port. The grating has a concave surface and a meridian plane with a first side and a second side. The lens has a substantially planar surface and a convex surface. Preferably, the convex and concave surfaces are substantially concentric. The ports are substantially located on different sides of the meridian plane near a focal plane of the spectrograph. The position of a focal plane may be modified using an optically transmissive triangular prism with a reflective surface, and an optically transmissive block. The position of a focal plane may further be modified with one or more optically transmissive plates. Methods for using the spectrograph are also provided.
