ABSTRACT:
Laser-scanning microscope with at least one detection radiation input, in which an aperture plate is installed in front of the detector, whereby optics with variable transmission lengths and a fixed focal distance is provided for focusing varying wavelengths of the detected light onto the aperture plate level at the detection radiation path, which realizes the imaging from the infinite space into an image level with a finite conjugate distance,and/orwith at least one light source launched via an optical fiber, whereby collimator optics with a fixed focal distance, and a variable conjugate distance are down-streamed from the fiber output, which transfers the point source at the fiber output with a numerical aperture into a parallel beam in the infinite space in front of the scan-objective lens, whereby a wavelength-dependent, at least partial compensation of the chromatic distortion of the micro-objective lenses occurs by means of turning the chromatic curve for the illumination wavelength used.
