Light microscopy monochromator

A typical experimental arrangement for Raman microscopy is shown in Fig. 3.25. The output beam of an argon laser or a dye laser is focused by a microscope objective into the microsample. The backscattered Raman light is imaged onto the entrance slit of a double or triple monochromator, which effectively supresses scattered laser light. A CCD camera at the exit of the monochromator records the wanted spectral range of the Raman radiation [364, 368, 369],...
