Abstract:
A laser scanning microscope for inspecting a specimen (3), said microscope comprising a laser light source (1, 2) defining an illumination beam path (4) extending between the laser light source (1, 2) and the specimen (3), a detection device (6) defining a detection beam path (7) extending between the specimen (3) and the detection device (6), at least one reference beam path (9) for reference measurement wherein reference light is coupled out of the illumination beam path (4) into the reference beam path (9) and the reference light is qualitatively and quantitatively detectable by the detection device (6), and a filter receiving element (13), wherein with the filter receiving element (13) either no light, or light from the detection beam path (7), or light from the reference beam path (9) can be selected through to the detection device (6).
