Abstract
A device for increasing the depth discrimination of optical imaging systems includes elements for structuring illumination light in an illumination beam of the optical imaging system by application of a grating-like pattern in a conjugate object plane of the optical imaging system. The device further elements for varying the position of the grating-like patterns along an optical axis of the illuminating beam, and elements that vary the position of an image of the grating-like pattern on a specimen in an object plane. The invention may include a grating changer connected to an electronic control system or to a control program of the optical imaging system for automatically changing the grating-like pattern to at least one further grating-like pattern and/or for removing the grating like pattern from the illuminating beam path.
