Abstract: A confocal scanning microscope has an illuminating beam path and at least one light source. The light of the light source is coupled into a fiber in which laser transitions can be induced. At least laser light induced in the fiber serves for specimen illumination after passing through an excitation pinhole.

Abstract: Apparatus for illuminating a specimen (1), preferably in confocal fluorescence scanning microscopy, has an illumination beam path (2) of one light source (3) and at least one further illumination beam path (4) of a further light source (5), the paths (2, 4) being at least partially superimposable on one another. In order to simplify alignment and reduce the optical components in the illumination beam path, at least one optical component (7) is arranged at least in one of the paths (2, 4) and modifies the light.

Abstract: An optical arrangement, in particular a microscope, having a light source 1 for illuminating an object, and a glass fibre 3, arranged between the light source 1 and the object, for transporting light along a prescribable distance between the light source (1) and the object. For avoidance of fluctuations in the illuminating light power without a handicap in the optical adjustment of the arrangement, the glass fibre 3 is a polarizing glass fibre 3. A polorisation-rotation device, such as g /2 plate 18, may be provided.

Abstract: The arrangement has a light source, especially a laser light source and an interruption device (1) for a light beam from the light source with a light barrier arrangement (3) for monitoring operation of the interruption device. The arrangement monitors the interruption state of the interruption device. There is a visual and/or an audible indication of a present and/or an absent interruption state. An Independent claim is also included for a shutter.

Abstract: Apparatus for combining light from at least two laser light sources (1, 2), such as in a confocal scanning microscope, employs laser light sources of low output power, the light from the sources having at least approximately the same wavelength. A beam combining unit (11) combines the light beams (12, 13) from the two sources in a substantially loss-free manner on the basis of at least one characteristic of the beams. This characteristic can be, for example, the light polarisation, in which case the beam combining unit (11) can be a polarisation beam splitter, phase of light, the pulse profile over time of light or the identical numerical aperture of a glass fibre (Fig 7). Master laser (24, Fig 5) may be combined with slave lasers (25-27, Fig 5). A Faraday rotator (17, Fig 2) or acousto-optical deflector (AOD) (38, Fig 6) may be used.

Abstract: The device has two tilting mirrors (1,2) for x and y deflection that rotate about 2 different axes (3,4). An optical device in the beam path (6) after one of the tilting mirrors forms a virtual image of the rotation axis of one mirror in a plane containing the rotation axis of the other mirror so that a common rotation point (10) for both deflections lies at the intercept of the virtual rotation axis (8) of one mirror and the real axis of the other mirror.

Abstract: An optical arrangement, in particular a laser scanning microscope, having a light source, in particular a laser light source, and an interruption device (1) for a light beam (2) of the light source, is configured, in the interest of reliable operation, in such a way that means (3) for monitoring the functioning of the interruption device (1) are associated with the interruption device (1). The invention additionally concerns a shutter (5) for a light beam (2) of a light source, in particular a laser light source, which, again in the interest of reliable operation of an optical arrangement, is characterized by at least two movable components (6, 7) which are configured and arranged such that the mechanical momentum generated by a moving component (6) or by several moving components is compensated for by the motion of the other component (7) or components.
