Abstract: A Raman spectrometer including a laser excitation source, edge filters, and detection optics that direct light into a spectrograph. A spectrograph containing a dispersive element and optics that directs various wavelengths of light onto a segmented diffractive MEMS light modulator array. The MEMS array, depending on actuation state, directs light either to or away from a single detector. Control electronics drive the MEMS light modulator for either sequential wavelength measurement or multiplexed wavelength measurement (Hadamard for example).

Abstract: An infrared light source includes a single-crystal ceramic element having at least two electrical contacts disposed thereon, such that the single-crystal ceramic element is stimulated to emit infrared light upon application of an electrical current through the at least two electrical contacts. The infrared light source further includes an evacuated housing enclosing the single-crystal ceramic element, the evacuated housing including an infrared transparent window.
