<p>A fluroscence spectral photometer has a light source and an excitation monochromator to separate monochromatic light from the source, whereby a monochromatic beam passes through an excitation exit slit. This beam is guided onto a sample by a system which forms an image of the slit. A similar arrangement produces an emission beam so that the excitation and emission beams intersect at the sample. A detector receives monochromatic light from the emission monochromator, whereby the two beam guide systems have slit imaging devices close to the sample and their longitudinal axes lie in the plane defined by the intersecting beams.</p> |
