Abstract
A compact, catadioptric and athermal imaging spectrometer is disclosed. A telecentric light () incident from a slit () is folded or refracted by an object-side prism () to enter a plano-convex lens (); after being refracted by the plano-convex lens () and a meniscus lens (), and refracted and reflected by a thick catadioptric lens (), said telecentric light is incident onto a convex grating () in the form of a convergent beam; and after said beam is diffracted, spectral division is implemented. The divergent beam is sequentially refracted and reflected by the thick catadioptric lens (), and refracted by the meniscus lens () and the plano-convex lens () to enter an image-side prism (). Said beam is folded or refracted and filtered, and imaged on a focal plane () to realize spectral imaging.
