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: Optical arrangement placed in the beam path of a laser scanning microscope has a light source and a spectral selection element (2). After the element (2) is an additional optical component (8). Once the light has passed through this element the dispersion and doubly refracting properties of the detection light can be detected. Typically optical components (2, 8) are acousto-optical-modulators or acousto-optical-deflectors.

Abstract: The present invention concerns an apparatus for combining light from at least two laser light sources, preferably in the context of confocal scanning microscopy, and in order to make laser light sources of low output power usable as light sources, in particular for confocal scanning microscopy, is characterized in that the light from the laser light sources has at least approximately the same wavelength; and that at least one beam combining unit that combines the light beams in at least largely lossless fashion is provided.

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: The device has an input (21) and output (22) each with a beam splitter (23,24) and in optical active positioning with these several deflection members (26,27,28,29) arranged to form three optical stretches measured so that at the output of the device the laser pulses coincide in time and spatially in the different optical stretches. The stretches are preferably whole number multiples of the spatial distances of the pulses. Independent claim describes method for reducing hissing of laser pulses by dividing up the laser light so that the pulses coincide in the three optical stretches. Independent claim describes microscope with device to reduce hissing wherein beam splitters are provided to produce the optical stretches.

Abstract: The device has an optical fiber (20) guiding light of several lasers (16a, 16b, 16c) to an optical system. A combining unit (18) is fastened on the mounting plate, and has several inlet ports (18a, 18b, 18c), where each laser has outlets (25a, 25b, 25c) for light. The lasers are mounted on a mounting plate (15) such that the outlets of the lasers are collinear with the respective inlet ports of the combining unit. The combining unit combines the light of the lasers to a single beam. An independent claim is also included for a microscope comprising several lasers that are arranged on a mounting plate.

Abstract: The scanning microscope (1) has an incoupling apparatus (31) with which light (33) other than the light (17) proceeding from the sample (7) is coupled into the detection beam path and conveyed to the detector (21). A closure apparatus automatically closes off the incoupling apparatus from the outside, in largely light-tight fashion, when the light guide (37) guiding the other light to the incoupling apparatus is removed. An independent claim is also included for confocal scanning microscope.
