Claim Text:
1. A laser scanning microscope (LSM) for use with a sample, the LSM comprising: at least one light source providing light, from which an illumination beam path emanates in the direction of the sample for illuminating the sample; a microscope lens, the illumination beam being focused as illuminating points by the microscope lens in a sample plane; a detector arrangement of at least one detector; at least one detection beam path for transferring sample light to the detector arrangement; a first adjustable, slit-shaped pinhole with a variable slit diaphragm for first confocal filtering before the detector arrangement; a scanner for generating a relative movement between the illumination light and the sample in at least one direction and through the microscope lens; a second, adjustable slit-shaped pinhole, with a variable slit diaphragm, arranged next to and downstream from the first pinhole so as to be optically conjugate to the first pinhole; and an image-rotating device for rotating the orientation of the illumination beam, arranged between the first and the second pinhole.
