Abstract

An optical assembly in a laser scanning microscope, having an optical scanning unit providing a first pupil plane, a first beam deflecting device, made of a first scanner arranged on the first pupil plane, for scanning excitation radiation in a first coordinate direction, a first focusing device generating a second pupil plane, optically conjugated to the first pupil plane, and a second beam deflecting device for deflecting the excitation radiation. The second deflecting device is arranged on the second pupil plane. A second focusing device to generate a third pupil plane, is optically conjugated to the first pupil plane and the second pupil plane. A third beam deflecting device is arranged on the third pupil plane, and a variable beam deflecting device is provided to switch an optical beam path between a first beam path and a second beam path.
