ABSTRACT:
A first monochromator includes a diffraction grating that is adapted for occlusion by a mirror. When the mirror occludes the grating, a white light input is transmitted through the first monochromator and through a sample under test, thereby causing a transmission of non-absorbed light from the sample. When the grating is unoccluded, monochromatic light is transmitted from the first monochromator so that a selected bandwidth of fluorescence excitation energy is incident on the sample. Fluorescence emission from the sample is diffracted by a second monochromator which provides diffracted light which is recorded by a vidicon.
