摘要： Optical switch for adjustable deflection of a light beam from the direction of an input point in the direction of one of several output points. The optical switch includes a switching mirror sensitive to changes in environmental conditions, such as temperature fluctuations. Also included is a rotatable capturing mirror, two beam splitters, and two spatially-resolving detectors. Both mirrors can be rotated around respective axes. A front beam splitter for the partial coupling of the light beam at the front detector that is optically positioned between the capturing minor and the switching mirror, while the back beam splitter for the partial decoupling of the light beam at the back detector is arranged optically between the switching mirror and each of the output positions. A control unit is adapted to control the drive of the switching mirror on the basis of a signal from the back detector.

摘要： A method and apparatus for actuating an acousto-optical component for manipulating light passing therethrough, in particular for manipulating the illumination and/or detection light in the beam path of a microscope, preferably a laser scanning microscope, where the illumination and/or detection wavelength is adjusted by means of at least one frequency generator connected to the acousto-optical component and controlling the manipulation, the frequency generator generates a signal which generates a spectral spread for the intensity distribution of the wavelength of the illumination and/or detection light for ensuring a temperature-independent manipulation. Actuation is effected by two or more actuation signals in such a way that two or more overlapping and/or superposing main lobes of the transfer function of the acousto-optical component or main maxima are generated.

摘要： The present invention relates to a device for driving a light source for a microscope, the device comprising: a current source, for supplying the light source with a coarse driving current, a small signal generator, for supplying the light source with a fine driving current. The sum of the coarse driving current and of the fine driving current results in a driving current for the light source, wherein the fine driving current has a magnitude smaller than the coarse driving current. The invention further relates to a method for controlling said device.
