Patent AT-E400000-T1: [Translated] LASER SCANNING MICROSCOPE WITH COLLIMATOR AND/OR PINHOLE OPTICS

Laser scanning microscope with at least one detection beam input, in which prior to the detector, at least one hole shutter is provided. For focussing different wavelengths of the detection light in the hole shutter plane an optical device is used with variable propagation lengths and fixed focal distance, which ensures imaging of an infinite space in an image plane of finite cross section. The invention also relates to a corresponding optical device for use in an inventive laser scanning microscope.
