A method and apparatus for tunably changing illumination light and / or sample light with respect to its spectral composition and / or intensity. In the method and apparatus, a first polarization means (Pol1) performs spatial separation into radiation components of different polarizations, and a first dispersion means (Disp1) performs spectral separation of at least one radiation component. Spatial division is performed, the polarization state of at least one portion of the spectrally and spatially divided radiation component is changed, and reflection of illumination light and / or detection light is performed.
