Scanning microscope

A scanning microscope comprising:

• at least one light source for generating an excitation light beam of a first wavelength and second light beam of a second wavelength,
• microscope optics for focusing the excitation light beam onto a first focal region in a first plane of a sample and for focusing the second light beam onto a second focal region in a second plane of the sample, whereby the excitation light beam optically excites the sample in the first focal region and the second light beam optically excites the sample in the second focal region, the first and second focal regions overlapping at least partially,
• said light source and said microscope optics defining an illumination beam path,
• a scanning device for scanning the excitation light beam and the second light beam onto the sample,
• components for guiding and shaping being arranged in the illumination beam path, whereby optical properties of the components and of the microscope optics are matched to one another such that optical aberrations are corrected in such a way that the focal regions remain static relative to one another irrespective of the scanning movement.
