Laser microscope system

A laser microscope system comprising:

• a microscope having a microscope table configured to receive a sample, an illumination device with a light source configured to illuminate the sample, and a lens which defines an optical axis and a rear focal plane of the lens and is arranged to image the sample;
• and
• a laser configured to generate a laser beam proliferating along a laser beam path and an optical laser system which is arranged downstream of the laser and which is configured to couple the laser beam into the microscope such that the laser beam passes through the rear focal plane of the lens at a fixed point and is focused by the lens on an object plane of the microscope in such a manner that the sample is cut by the laser beam,
• wherein the lens is movable in a direction of the optical axis so as to adjust a visual illumination focus, and whereby a movement of the lens causes a shift of the rear focal plane of the lens,
• wherein the optical laser system has an offset lens which is movable along an axis of the laser beam path so as to move a focus of the laser beam in a direction of the optical axis of the lens such that the focus of the laser beam coincides with the visual illumination focus,
• wherein the optical laser system has a compensating lens which is arranged in the laser beam path and is movable along the axis of the laser beam path, or wherein the optical laser system is mounted at least partially on a slide movable along the axis of the laser beam path and
• wherein a controller and/or a mechanical coupling device is configured to carry out a movement of the compensating lens along the axis of the laser beam path, or to carry out a movement of the slide, based on the lens being moved so as to compensate movement of a point of impingement of the laser beam on the rear focal plane caused by movement of the lens such that the laser beam continues to pass through the fixed point of the rear focal plane of the lens and stays focused onto the sample.
