Abstract: A microscope comprises an objective and a light source that produces an illumination light beam-in particular for evanescent illumination of a sample, which exhibits a focus in the plane of the objective pupil. To adjust the penetration depth, an adjustment mechanism is provided with which the spatial position of the focus within the plane of the objective pupil may be changed.

Abstract: Device for determination of the light intensity of a light beam (7) has a beam splitter (1) and a detector (11). The beam splitter divides off a measurement beam (23) from the incident beam and the ratio of the intensity of the light in the incident beam to that of the measurement beam is measured using the detector to ensure that the ratio remains constant. Beam splitter and detector form a single unit. Independent claims are also made for: (1) A microscope; (2) A microscopy method in which the intensity of the incident illumination beam is monitored.

Abstract: The microscope has a scanning head (2) comprising a scanning device (1) for light beams, and a scanning tube lens (3). The tube lens is coupled with the scanning head for forming a common module, where the lens is adapted to the optical requirements of the scanning device and/or the scanning head. A scanning eyepiece is arranged in the scanning head, and another lens tube is adapted to the requirements of a visual observation.

Abstract: A scanning microscope includes a light source for evanescently illuminating a sample disposed on a slide. A point detector receives detection light emanating from a scanning point of the sample. A beam deflection device disposed in an optical path of the detection light can shift a position of the scanning point.

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: 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.
