Abstract
A spectrometer includes: a collimating element configured for collimating a beam of light into a first one of a cross-dispersing element and an echelle grating, the grating in optical communication with the cross-dispersing element; a focusing element for receiving the light from a second one of the cross-dispersing element and the echelle grating and focusing wavelengths of the light onto a spatial light modulator; the spatial light modulator configured for selectively directing the wavelengths onto a detector for detection. A method of use and the method of fabrication are provided.
