Abstract

A process for confocal microscopy is disclosed in which laser light is coupled into a microscope beam path, directed successively with respect to time onto different locations of a specimen, and an image of the scanned plane is generated from the light reflected and emitted by the irradiated locations. A change in the spectral composition and in the intensity of light is are carried out during the deflection of the laser beam from location to location, while the deflection continues in an uninterrupted manner. In this way , so that at least two adjacent locations of the specimen located next to one another are acted upon by light with different spectral characteristics and by laser radiation of different intensity. By periodically interrupting the coupling in of the laser light during the deflection of the microscope beam path, it is made possible that only selected portions of the image field are acted upon by the laser radiation. A laser scanning microscope for carrying out this process is also disclosed. A laser scanning microscope for carrying out this process is also disclosed.
