Abstract:
1. A laser scanning microscope comprising: an illumination beam path of illumination light; a detection beam path of detection light; a first beamsplitter which reflects the illumination light in a direction of a sample, and transmits the detection light in a direction of a detection arrangement; and a second beamsplitter which reflects the illumination light and transmits the detection light; wherein the second beamsplitter is arranged in the illumination beam path downstream of the first beamsplitter in an illumination direction; wherein the second beamsplitter transmits the illumination light reflected at the first beamsplitter and the detection light, but acquires a wavelength range different from the first beamsplitter with respect to the reflectivity of the second beamsplitter; wherein a wavelength region of reflection for the first beamsplitter lies substantially in the visible region, and a first wavelength region of the second beamsplitter lies substantially in the edge area of the visible light region and outside the visible region; and wherein the second beamsplitter has a second reflectivity region which is adapted to the wavelength region of a tunable laser in the visible region.
