Spectralfluorometer arrangement

摘要

The invention relates to a spectral fluorometer arrangement including at least one laser light source, particularly for use in measuring the luminescence in the course of a qualitative and quantitative determination of a sample material, the region of which to be excited is arranged in the object point of an emission monochromator and spectrograph, respectively, a holographic grating of said monochromator being provided with a central opening for passage of the exciting laser beam, and beam directing means are provided outside of the plane of symmetry of said emission monochromator and spectrograph, respectively.
