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: A sample cell for a spectrometer, and a spectrometer using such a sample cell. The sample cell may include a housing having a reflective inner surface which is at least a section of a spheroid bounding a cavity. A lens system receives electromagnetic radiation from a source and directs a converging beam through a port in the cavity to a focal point inside the cavity, such that the beam undergoes multiple reflections on the inner surface before exiting the cavity. Arrangements for adjusting beam cross-sectional area and angle are optionally provided. Methods which can be performed on such an apparatus and computer program products for performing such methods are further provided.
