  • Patent number: 8472113
    Abstract: A scanning microscope includes a light source, illumination optics, and a scanning device for moving the illumination focus across a target region and doing so by varying the direction of incidence in which the illuminating beam enters an entrance pupil of the illumination optics. To incline the illumination focus relative to the optical axis of the optics, the scanning device directs the illuminating beam onto a portion of the entrance pupil that is offset from the center of the pupil and, in order to move the illumination focus across the target region, the scanning device varies the direction of incidence of the illuminating beam within said portion. An observation objective is provided which is spatially separated from the illumination optics and disposed such that its optical axis (O3) is substantially perpendicular to the target region and at an acute angle (?) to the optical axis (O1) of the illumination optics.

  • Publication number: 20110222147
    Abstract: An apparatus in a simultaneous fluorescence excitation microscope is described, allowing simultaneous fluorescence excitation by light of at least two different wavelengths. The apparatus has a laser light source generating a light beam. A first beam splitter splits the light beam into a first partial light beam and a second partial light beam. A wavelength converter converts the wavelength of the first partial light beam. A microscope optical system into which the first partial light beam and the second partial light beam are coupled directs the two partial light beams onto an object to be examined.

  • Patent number: 7660035
    Abstract: A scanning microscope includes at least one light source, an acousto-optical element, a beam deflection device and a beam guiding device. The at least one light source generates an illuminating light beam. The acousto-optical element spatially splits a sub-light beam from the illuminating light beam and adjusts an optical power of the illuminating light beam. The beam deflection device scans the illuminating light beam over or through a sample. The beam guiding device directs the sub-light beam onto the sample.

  • Patent number: 7633622
    Abstract: A microscope with evanescent sample illumination and a method for testing samples are disclosed. A first evanescent field, which exhibits a first penetration depth in the sample, and a second evanescent field, which exhibits a second penetration depth in the sample that is greater than the first penetration depth, are produced. A detector is provided that detects the first detection light, which exits from the part of the sample illuminated with the first evanescent field, and which produces first detection light data therefrom, and the second detection light, which exits from the part of the sample illuminated with the second evanescent field, and which produces second detection light data therefrom. Furthermore, a processing module is provided for processing the first and second detection light data.

  • Patent number: 7564624
    Abstract: The invention relates to a microscope comprising at least one first and second light sources, a first light-guiding fiber connected to the first light source and a second light-guiding fiber connected to the second light source, wherein the light emitted by corresponding light source is injectable into the connected light-guiding fiber. The inventive microscope also comprises an objective lens disposed in the illumination beam path and is characterized in that a fiber multiplexer connected to the first and second light-guiding fibers, receiving the light from the light source and selectively allowing the light from the first or second light source to pass is disposed in the illumination beam path.
