Classification: CPC G | IPC G

Claim 14:
15. A detection apparatus for detecting emission light in a laser scanning microscope, the detection apparatus comprising:
a two-dimensional matrix sensor in an image plane with a multiplicity of pixels for spatially oversampled detection of a detection point spread function of emission light coming from a sample and comprising an imaging optical unit for guiding the emission light to the two-dimensional matrix sensor,
a dispersion device for spectrally separating the emission light, wherein the matrix sensor is configured and positioned for separately detecting the spectrally separated emission light, and
evaluation electronics connected to the matrix sensor for evaluating intensities measured by the pixels of a pixel region of the detection point spread function, wherein the evaluating includes reversing the spectral separation for at least some of these pixels,
wherein, in order to reverse the spectral separation for the at least some of the pixels of the pixel region, the evaluation electronics are configured to assign intensity values measured by the pixels to a location in the image plane that has been displaced relative to the respective pixel, using a displacement vector depending on the location of the respective pixel and a wavelength associated with that location.
