Abstract: A scanning microscope includes at least one light source, an acousto-optical element, a beam deflection device and a beam guiding device. The at least one light source generates an illuminating light beam. The acousto-optical element spatially splits a sub-light beam from the illuminating light beam and adjusts an optical power of the illuminating light beam. The beam deflection device scans the illuminating light beam over or through a sample. The beam guiding device directs the sub-light beam onto the sample.

Abstract: A microscope possesses at least one illumination source for emitting electromagnetic radiation, an objective holder, and a detector. Also provided is a detection device which is configured so that it detects whether an element is inserted in the objective holder. The detection device is coupled to a blocking device for interrupting the electromagnetic radiation.

Abstract: The microscope has an illumination beam path between a laser light source (1,2) and an object (3), and a detection beam path (7) between the object and a detector (6). At least one reference beam path (9) is provided for reference measurements. Reference light is coupled from the illumination beam path into the reference beam path. The reference light is qualitatively and/or quantitively detected by the detector (6). A scattering optical component (11) and/or a beam deflector (25) may be arranged in the reference beam path. An Independent claim is included for a method of reference correction in a laser scanning microscope.

Abstract: The arrangement has at least one spectrally selective element (4) for coupling the stimulation light from at least one light source (2) into the microscope and for stopping the stimulation light reflected and scattered at the object (10) and the stimulation wavelengths from the light passing from the object over the detection beam path (12). Stimulation light of different wavelengths can be stopped by the spectrally selective element.

Abstract: Eine Vorrichtung umfasst zur simultanen Fluoreszenzanregung ein Fluoreszenzmikroskop. Die Vorrichtung hat eine Laserlichtquelle (20), die einen Lichtstrahl (22) erzeugt. Ein erster Strahlteiler (24) teilt den Lichtstrahl (22) in einen ersten Teillichtstrahl (26) und einen zweiten Teillichtstrahl (28) auf. Ein Wellenlängenkonverter (30) konvertiert die Wellenlänge des ersten Teillichtstrahls (26). Eine Mikroskopoptik (38), in die der konvertierte erste Teillichtstrahl (32) und der zweite Teillichtstrahl (28) eingekoppelt werden, richtet die beiden Teillichtstrahlen (28, 32) auf ein zu untersuchendes Objekt.

Abstract: The invention relates to an optical arrangement provided for a spectral fanning out of a light beam (1), preferably the detection beam path of a confocal microscope, especially for the subsequent splitting of the fanned out beam (2) out of the dispersion plane thereof. The optical arrangment is also provided for detecting the fanned out spectral regions (4), whereby the incoming light beam (1) is focused on a pinhole (7). The invention is characterized in that the pinhole (7) has a polygonal passageway (8) in order to realize a high dynamic response when the light beam is split into spectral regions (4) or into spectral colors.
