Optical arrangement for use in deflection beam path of laser-scanning-microscope, has polarization device provided upstream to dispersive element in deflection beam path and adjusting polarization direction for light detection

摘要

The optical arrangement has a dispersive element e.g. prism or lattice, for spectral split-up of detected light in spectral components. A polarization device is provided upstream to the dispersive element in a deflection beam path. The polarization device adjusts a polarization direction for light detection. A Lambda 1/2 plate is rotatably and/or demountably arranged downstream to a polarizer in the polarization device for generating a polarization plane. The polarization device and the Lambda 1/2 plate are formed as films.
