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: The arrangement has a scanning microscope e.g. confocal microscope, and a laser formed as a pulsed laser (1). An optical component is positioned between the laser and a lens (12), where light generated by the laser is spectrally processed by a unique cycle such that a spectral illumination light is emitted from the laser. An optical fiber (20) forms the optical component, and is comprised of photonic-bad-gap material. An optical diode is provided between the laser and fiber for suppressing back reflection of light rays originated from ends of the fiber.

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 arrangement has at least one light source for simultaneous illumination of specimen points (2) with stimulation light and a detection arrangement with detection elements (3) for simultaneous detection of the fluorescent light from the individual specimen points. The distance (d) between the specimen points and the associated detection elements is chosen to be as small as possible.

Abstract: The invention relates to a microscope, in particular a confocal microscope, designed to measure an object from several angular positions while avoiding any rotation of the object to be measured. The microscope has an optical device for rotation of the image to be positioned in the ray path of the microscope.

Abstract: An arrangement for optically scanning an object, more particularly used in preferably confocal laser scan microscopy, whereby a lens or an objective (3) and at least one scanning mirror (4) are arranged inside the the illuminating /detecting beam (1,2). In order to scan object fields whose size is greater than the optic system of the microscope with sufficiently rapid acquisition of data, using simple optical components, the invention is characterized in that the mirror (4) can rotate or pivot around an axis of rotation (5) that is at least substantially orthagonal with respect to the scanning surface of the object.

Abstract: An arrangement (3) allows spectral fanning out of the light beam (1) and an arrangement (4) splits the fanned out beam (5) out of the dispersion plane (6) and into spectral ranges. Subsequently detection of the fanned out spectral ranges is executed.
