Abstract: A method for examining a specimen ( 27 ) that exhibits at least two optical transition lines and is optically excitable at least with light of a first and light of a second wavelength is characterized by the step of illuminating the specimen ( 27 ) with illuminating light ( 15 ) that generates at least a multiple of the first wavelength and a multiple of the second wavelength; and by the step of detecting the detected light ( 29 ) proceeding from the specimen ( 27 ). Also disclosed is a scanning microscope system ( 1 ) having at least one light source ( 3 ) that emits illuminating light ( 15 ) for illumination of a specimen ( 27 ), the specimen ( 27 ) exhibiting at least two optical transition lines and being optically excitable at least with light of a first and light of a second wavelength, having at least one detector ( 41, 43, 65, 77, 79 ) for detection of the detected light ( 29 ) proceeding from the specimen ( 27 ) and an objective ( 25 ) for focusing the illuminating light ( 15 ) onto a subregion of the specimen ( 27 ). The scanning microscope system is characterized in that the illuminating light ( 15 ) generates at least a multiple of the first wavelength and a multiple of the second wavelength.

Abstract: The present invention concerns a microscope and a method for operating a microscope, in particular a confocal or double confocal scanning microscope, having an optical beam path (9) extending between a light source (1), a specimen (2), and a detector (7) and/or a detection optical system, in which context intentional and unintentional relative motions occur between the specimen (2) and the optical beam path (9), undesired relative motions of the microscope components in optical beam path (9) are intended to result in no (or only minor) image defects, and method steps are provided which eliminate or minimize the image defects brought about by undesired relative motions between the specimen (2) and optical beam path (9); and is characterized in that a first device (8) detects relative motions; and a second device (22) compensates for unintentional relative motions.

Abstract: An apparatus for illuminating a specimen (1), preferably in confocal fluorescence scanning microscopy is disclosed. Two illumination beam paths (2, 4) are combined with a beam splitter (6) in order to simplify alignment and reduce the optical components in the illumination beam path. The at least one optical component (7) is arranged at least in one of the illumination beam paths (2, 4) and modifies the light; and that the optical properties of the component (7) can be influenced or modified in such a way that the illumination pattern of the illumination beam path (2, 4) in the specimen region changes shape.

Abstract: Light from a source (3) is coupled into a fiber (4) and induces excitation transitions in the fiber. The light induced by the excitation transitions is used to illuminate the objects (2). The fiber may be suitable for fluorescent excitation. The device may include an acousto-optical tunable filter or LCD attenuator.

Abstract: A method for examining a specimen (11) by means of a confocal scanning microscope having at least one light source (1), preferably a laser, to generate an illuminating light beam (4) for the specimen (11), and a beam deflection device (9) to guide the illuminating light beam (4) over the specimen (11) comprises, in the interest of reliable definition of details or regions of interest of the specimen (11), the following method steps: Firstly a preview image is acquired. Then at least one region of interest in the preview image is marked. This is followed by allocation of individual illuminating light beam wavelengths and/or illuminating light beam power levels to the region or regions. Illumination of the region or regions of the specimen (11) in accordance with the allocation is then accomplished, at least one manipulation in at least one region (25) being performed by means of the illumination. Also described is a confocal scanning microscope having at least one light source (1), preferably a laser, to generate an illuminating light beam (4) for a specimen (11), and a beam deflection device (9) to guide the illuminating light beam (4) over the specimen (11), means for acquiring a preview image and means for marking at least one region of interest in the preview image being provided, such that individual illuminating light beam wavelengths and/or illuminating light beam power levels can be allocated to the region or regions, and the region or regions of the specimen (11) can be illuminated in accordance with the allocation, and such that at least one manipulation in at least one region (25) can be performed by means of the illumination.
