摘要:
An optical arrangement having an optical assembly (1) for generating an intermediate image (2) in a beam path is configured and further developed such that an optical element (3) having a plurality of optical waveguides (4) is arranged in the beam bath after the intermediate image (2) to enable the imaging of the intermediate image (2) in a plane on a zone-by-zone or point-by-point basis. Further, a microscope exhibiting such an optical arrangement is specified.
摘要:
A scanning microscope, having a detector, arranged in a detection beam path, for receiving detection light proceeding from a sample, has between the sample and the detector an optical shutter means with which the detection beam path can be blocked. A control means for controlling the shutter means is provided. The detection light beam path can be blocked automatically outside the scanning operation and in the event of an excessive detection light power level.

An apparatus for mounting for multiple lasers (16a, 16b, 16c) is disclosed. The multiple lasers (16a, 16b, 16c) generate light that is guided via a light-guiding fiber to an optical system (10). Provided for that purpose on the mounting plate (15) is a combining unit (18) that comprises multiple input ports (18a, 18b, 18c). Each of the lasers (16a, 16b, 16c) possesses an output (25a, 25b, 25c) for its light, each laser (16a, 16b, 16c) being mounted on the mounting plate (15) in such a way that the respective output (25a, 25b, 25c) is colinear with the respective pertinent input port (18a, 18b, 18c) of the combining unit (18). The combining unit (18) combines the light of the multiple lasers (16a, 16b, 16c) into a single beam (30).

A microscope includes a scanning head including a scanning device for a light beam. A scanning tube lens is coupled to the scanning head. The scanning head may be a scanning head of a scanning microscope. The scanning tube lens may be disposed inside the scanning head. The scanning tube lens may be adapted to an optical requirement of the scanning head.

With an eye towards achieving a particularly simple structure, a microscope with an objective (1) and/or an objective changer and/or an objective turret as well as adjustment means (3) for positioning a specimen stage is configured and refined in such a way that the objective (1) and/or the objective changer and/or the objective turret is/are coupled to the adjustment means (3) in such a way that the position of the objective (1) and/or the objective changer and/or the objective turret can be adjusted by the adjustment means (3).
摘要:
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.
摘要:
A method for separating different emission wavelengths in a scanning microscope includes scanning a specimen with an illuminating light beam by passing the illuminating light beam over the specimen using a beam deflector, and selectively applying each of a plurality of excitation wavelengths to the illuminating light beam during the scanning according to a predefinable illumination scheme. Emission light coming from the specimen is detected using a detector, the emission light including emission wavelengths corresponding to the excitation wavelengths. The detector is read out when an excitation wavelength is applied so as to provide detected signals. The detected signals are associated with the respective excitation wavelengths using the illumination scheme.
摘要:
A detector, arranged in the detection beam path of a scanning microscope, for the detection of detected light proceeding from a sample can be used to detect other than the detected light for example of external optical experiments. The scanning microscope comprises an incoupling apparatus with which light other than the detected light can be coupled into the detection beam path and conveyed to the detector.
