Abstract:
1. Laser-scanning microscope comprising: at least one detection radiation input, a detector, a pinhole installed in front of the detector, pinhole optics with variable transmission lengths and a fixed focal distance for focusing varying wavelengths of detected light onto the plane of the pinhole on a detection radiation path, which realizes imaging from infinite space into an image level with a finite conjugate distance, an optical fiber having an output, at least one light source launched via the optical fiber, a scan-objective lens a plurality of microscope-objective lenses, and collimator optics with a fixed focal distance and a variable conjugate distance down-stream from the fiber output, for transferring 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, wherein the collimator optics include:
