ABSTRACT:
Apparatuses and methods for performing spectroscopy and optical microscopy are disclosed. In at least one embodiment, a Raman spectrometer includes a vacuum ultraviolet light source configured to generate light having a wavelength within a window in the vacuum ultraviolet region of the electromagnetic spectrum within which a local minimum in the absorption coefficient of Oxygen occurs. The spectrometer also includes a lens device that receives a first portion of the generated light, directs at least some of the first portion of the generated light toward a target location, receives reflected light from the target location, and directs the reflected light toward a further location. The spectrometer further includes a dispersive device that receives at least some of the reflected light and outputs dispersed light produced based thereupon, and a camera module that is positioned at additional location, where the camera module receives at least some of the dispersed light.
