    摘要: An optical device for illuminating a sample located in a sample volume with illumination light and for detecting scattered and/or fluorescent light from the sample includes an optical illumination assembly, an optical detection assembly and at least one attachment element. The optical illumination assembly is configured to transmit the illumination light along an illumination path into the sample volume. The optical detection assembly is configured to collect and relay the scattered and/or fluorescent light from the sample volume along a detection path. At least portions of the illumination path and/or of the detection path extend in the at least one attachment element.

    摘要: A method forms a digital value from a clock signal and a digital data signal. The method includes sampling the clock signal in order to obtain a clock signal digital value sequence and sampling the digital data signal in order to obtain a data signal digital value sequence. Sampling points are ascertained from the clock signal digital value sequence, at which data signal digital values are extracted from the data signal digital value sequence. The digital value is formed from the data signal digital values.

    摘要: A method for adjusting an intensity of a light beam in an optical arrangement includes passing the light beam through an acousto-optical tunable filter (AOTF). The intensity of the light beam is adjusted as a function of frequency and/or amplitude of a sound wave with which the AOTF is operated. The amplitude of the sound wave at a specified sound wave frequency is selected such that the amplitude is larger than would be required to achieve a first maximum diffraction efficiency for a specified wavelength or for a specified wavelength spectrum of the light beam. The amplitude of the sound wave is also selected such that a value of an integral of a product of the transmission function of the AOTF and the wavelength spectrum of the light beam is larger than at a value of the amplitude to be selected to achieve the first maximum.

    摘要: A method for scanning a sample using an electrically or electronically controllable microscope includes performing a continuous scanning of the sample so as to repeatedly generate a plurality of images of the sample, each of the plurality of images corresponding to a different time, the microscope being controlled via a control computer during the scanning. The plurality of images are analyzed using at least one second computer connected via a network, wherein the at least one second computer is configured to classify each of the plurality of images as one of interesting and non-interesting while the continuous scanning of the sample with the microscope continues. The continuous scanning of the sample is automatically influenced based on the classifying of the images performed by the at least one second computer.

    摘要: A fluorescence microscope has an incident fluorescence illumination unit generating an incident fluorescence illumination beam path a multi-band fluorescence filter system encompassing a multi-band beam splitter for deflecting the incident fluorescence illumination beam path into an objective of the microscope and onto a specimen. The filter system has a multi-band blocking filter that at least partly transmits a fluorescence emission beam path proceeding from the specimen; and having a digital camera for generating a fluorescence image of the specimen. The microscope has a bright-field transmitted illumination unit for generating a bright-field transmitted illumination beam path for transmitted illumination of the specimen. The filter system is arranged fixedly so that upon acquisition of a bright-field image of the specimen, the system remains in a bright-field transmitted light beam path proceeding from the specimen. The digital camera has a white balance function that is executed before the bright-field image is generated.

    摘要: An illumination apparatus for a microscope, for producing a de-excitation or switching light distribution, includes a light source configured to produce a primary illumination light beam and a beam splitter configured to divide the primary illumination light beam into two partial illumination light beams. An illumination objective is configured to focus the partial illumination light beams onto and/or into a sample such that the partial illumination light beams extend, spatially separated from one another, through an entry pupil of the illumination objective and are spatially superposed on and/or in the sample after passing through the illumination objective. A phase influencer is configured to cause a relative phase offset of the partial illumination light beams with respect to one another in such a way that the partial illumination light beams in the entry pupil of the illumination objective have a phase offset of π.
