Abstract:
A confocal scanning microscope comprising an objective (5) and a condenser on opposite sides of an object (6), a light source (1) defining exciting light (2) for illuminating said object (6), a scanning device (4), a condenser-side detection light (8) and an objective-side detection light (9) being generated in the object (6) wherein the condenser-side detection light (8) and the objective-side detection light (9) define at least two detection channels, a superimposing device (11, 12, 13, 15, 17, 18, 21, 22, 25, 26, 27) for optically superimposing the at least two detection channels at a location outside an optical path connecting said scanning device and said object, a detector assembly with at least one detector (19, 20; 23, 24) for detecting the condenser-side detection light (8) and the objective-side detection light (9), and at least one means located in the optical path connecting said scanning device and said detector assembly for directing the detection light to said superimposing device.
