Abstract
The method for splitting and reflecting beams in a laser scanning microscope which produces a laser beam (,) comprises the steps of: reflecting a beam from a partially reflecting mirror (,); splitting the laser beam (,) with a splitting device into partial beams (,); causing the partial beams to travel in a plane; directing the partial beams to a sample under investigation; providing the partially reflecting mirror (,) with a constant transmission; placing the partially reflecting mirror between two high reflectivity mirrors (,); transmitting the laser beam (,) to one of the high reflectivity mirrors (,); reflecting said beam (,) to the other one of the high reflectivity mirrors (,) with basically equal attenuation; repeatedly transmitting the beam to one of the mirrors; and repeatedly reflecting the beam to the other one of said mirrors (,); arranging the partially reflecting mirror and the high reflectivity mirrors (,) relative to each other to cause beams (,) reflected by the partially reflecting mirror (,) not to coincide with beams reflected by said high-reflectivity mirrors (,); shifting forwardly, at an exit region of the splitting device, an edge of the partially reflecting mirror (,) along an edge of one of the high-reflective mirrors (,); and shifting rearwardly an edge of the other high-reflective mirror (,).
