Abstract: A compact spectrometer apparatus for characterizing a microscope illumination source in real time, and without interfering with the observation and/or characterization of a sample under observation with the microscope. The spectrometer apparatus is comprised of a light probe comprising a mirror disposed in a housing, the mirror positioned to reflect light from the illumination source into an optical coupling; an optical waveguide receiving reflected light into the optical coupling; and a spectrometer comprising a light sensor receiving reflected light directed by the optical waveguide from the optical coupling of the light probe, the sensor adapted to sense light over a range of wavelengths and output a signal indicative of the intensity of the light at any wavelength over the range.
