Abstract:
1. A device for confocal observation of a specimen, comprising an objective, a mask, which is located in an illumination beam path and an image beam path and which is rotatable around a central axis, the mask being imaged onto the specimen by means of the objective and being provided with openings for generating an illumination pattern moving on the sample, an arrangement of a plurality of focussing microoptics which is adjusted to the geometric arrangement of the openings of the mask and to the rotation of the mask in order to concentrate the illumination light by each of the microoptics into a respective one of the openings of the mask, and a beam splitter for separating light from the sample which has been collected by the objective and which has passed through the openings of the mask from illumination light, wherein the beam splitter is arranged in the beam path between the mask and the arrangement of the microoptics, wherein the openings of the mask and the microoptics arrangement are arranged fixed to each other and concentric around the central axis, with the openings of the mask and the microoptics arrangement being radially displaced with regard to each other.
