Abstract

An optical assembly for scanning excitation radiation and/or manipulation radiation in a laser scanning microscope. The assembly an optical scanning unit as a first focusing device for providing a first pupil plane, a first beam deflecting device, which is made of a first scanner arranged in the first pupil plane, for scanning the excitation radiation and/or manipulation radiation in a first coordinate direction, and a second focusing device for generating a second pupil plane, which is optically conjugated to the first pupil plane. A second beam deflecting device is provided for deflecting the excitation radiation and/or manipulation radiation, said second deflecting device being arranged in the second pupil plane. A third focusing device is provided in order to generate a third pupil plane, optically conjugated to the first pupil plane. A third beam deflecting device is arranged in the third pupil plane in order to deflect the excitation radiation and/or manipulation radiation, and a variable beam deflecting means is provided in order to switch an optical beam path between a first beam path and a second beam path.
