Abstract: A condenser unit for providing directed lighting of an object to be measured positioned in a measured object position, wherein the condenser unit comprises a light source for emitting a light beam and an optical element having a positive refractive power. The condenser unit further comprises at least one attenuation element arranged in a common optical axis with the light source and the optical element, which attenuation element comprises a location-dependent light intensity attenuation effect for the light beam incident on the attenuation element, more particularly wherein the light intensity attenuation effect declines from the optical axis towards an edge of the attenuation element.

Abstract: The invention relates to an apparatus for simultaneously analysing luminescence of a plurality of samples. The apparatus comprises a fibre-optic plate.

Abstract: The invention is directed to a method and an arrangement for high-resolution microscopic imaging in laser endoscopy based on laser-induced object reaction radiation and for performing microscopic cuts in biological tissue. In using multiphoton processes for endoscopic applications in biological materials with an accuracy of under one millimeter, radiation of a pulsed femtosecond laser is focused into an object by means of a transmission focusing optics unit comprising a transmission system and miniature focusing optics having a high numerical aperture greater than 0.55 to trigger a local object reaction radiation in the micrometer to nanometer range, and the distal end of the transmission focusing optics unit is moved in at least two dimensions for highly spatially resolved scanning of the object and for transmitting object reaction radiation which is scanned in a locally progressive manner to an image-generating system with a photon detector.
