    Abstract: Separating different emission wavelengths in a scanning microscope, is new. Separating different emission wavelengths in a scanning microscope comprises: (a) scanning a specimen with an illuminating light beam by passing the illuminating light beam over the specimen using a beam deflector; (b) selectively applying each of excitation wavelengths (1, 2, 3) to the illuminating light beam during the scanning according to a pre-definable illumination scheme; (c) detecting emission light coming from the specimen using detector(s), where the detector is read out upon each selective applying of a respective excitation wavelength to provide respective corresponding detected signals; and (d) associating the detected signals with the respective excitation wavelength using the illumination scheme. The emission light includes emission wavelengths corresponding to the excitation wavelengths. An independent claim is also included for an apparatus for separating different emission wavelengths in a scanning microscope, comprising: (a) light source(s) configured to generate an illuminating light beam; (b) a beam deflector configured to scan a specimen with the illuminating light beam by passing the illuminating light beam over the specimen; (c) a light control device configured to selectively apply each of excitation wavelengths to the illuminating light beam during a scanning according to a pre-definable illumination scheme; (d) detector(s) configured to pick up emission light coming from the specimen; and (e) a processing device configured to associate the detected signals with the respective excitation wavelengths using the illumination scheme.

    Abstract: The invention concerns a method and an apparatus for investigating layers ( 1 ) of tissues in living animals using a microscope ( 2 ). The microscope ( 2 ) is focused onto a layer ( 1 ), and images of the layer ( 1 ) are acquired or optical measurements are performed on it. Positional changes of the layer ( 1 ) are brought about by movements of the animal or of its organs. The positional changes are sensed, and corresponding signals are generated. The signals are stored, together with the corresponding images or measurement results, for later evaluation; or they are processed in such a way that the positional changes are compensated for in order to investigate the layer ( 1 ). As a result, the layer ( 1 ) can be qualitatively or quantitatively investigated microscopically, irrespective of the movement of the animal or its organs.

    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.
