Device for positioning an optical element in a ray path

A device for positioning an optical component (1) in a beam path (2), preferably in the beam path (2) of a microscope, in particular a confocal scanning microscope, wherein a plurality of optical components (1) in a socket (3) are arranged, is characterized in that the holder (3) is guided as a magazine (3) in a guide block (5) positioned in the beam path (2) and having a passage (4) for the beam path (2). Furthermore, for a simple, fast and precise replacement of the optical elements while avoiding an always required adjustment of the optical components, a device for positioning an optical component in a beam path (2), preferably in the beam path of a microscope, in particular a confocal scanning microscope, characterized
