Abstract: One embodiment provides an apparatus for facilitating raster scanning of an optical spectrometer. The apparatus can include an enclosure, a lens holder situated within the enclosure, and an actuation mechanism coupled to the lens holder. The lens holder is configured to hold a lens that focuses excitation light onto a sample surface, and the actuation mechanism is configured to cause the lens holder to perform a motion according to a predetermined pattern, thereby causing the focused excitation light to raster scan the sample surface.

Abstract: One embodiment provides an optical spectrometer. The optical spectrometer can include a lens-and-filter system configured to collect light scattered from a sample, a spot converter configured to convert a substantially circular beam outputted from the lens-and-filter system into a substantially rectangular beam, and a slit comprising a rectangular aperture to allow a predetermined portion of the substantially rectangular beam to enter the rectangular aperture while blocking noise. The slit can further include at least one microelectromechanical systems (MEMS)-based movable structure configured to adjust a width of the rectangular aperture.
