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.
