Abstract: An apparatus includes a housing and a chamber. The chamber is configured to hold analyte. The chamber includes a reflective element, either a reflective coated layer or a reflective mirror, to return optical signals entering the analyte. A window is coated with an anti-reflective material or has negligible optical interference. A cap seals the chamber and the housing. A flow channel is provided within the housing and the chamber assembly to allow the analyte to flow through with reduced bubble entrapment as the cap is tightened to seal the chamber assembly.

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.
