Abstract
An apparatus for optical spectrometry utilizes a simplified construction, reducing the number of independent optical elements needed while providing a sizeable dispersed spectrum. The apparatus provides a spectral intensity distribution of an input source wherein individual spectral components in the source can be measured and, in some embodiments, can be manipulated or filtered.
Claims3
A compact optical multiplexer/demultiplexer system, comprising:
- a grating and a two element optical system in which a focal length of said optical system is minimized over a single lens such that a round trip optical path is contained within a compact optical footprint, said optical system operating near Littrow and exhibiting telecentricity, said optical system providing that light comes in and goes out from a common direction, wherein the optical footprint of said compact design is on the order of 6×8 inches and said optical multiplexer/demultiplexer has an optical centerline and said grating is to one side of said centerline.
