Abstract:
1. Device usable for changing at least one of the illumination light and the specimen light of a microscope with respect to at least one of its spectral composition and intensity, and for separating the illumination light from the specimen light, comprising: first polarization means for spatially separating at least one of the illumination light and the specimen light of the microscope into radiation components of different polarization directions, first dispersion means for spectrally spatially splitting at least one radiation component downstream of the first polarization means, and for re-combining the at least one spectrally spatially split radiation component in an upstream direction, imaging optics for imaging the at least one spectrally spatially split radiation component from the first dispersion means onto a focal plane, means at the focal plane for changing the polarization direction of at least one part of the at least one spectrally spatially split radiation component, and tiltable reflection means for spatially shifting the radiation component having a changed polarization direction and reflecting it back through the imaging optics so that a variety of polarization directions reach different spots of the first dispersion means.
