Abstract:
A device for the production of a light beam having several wavelengths, particularly an illuminating light beam for a preferably confocal scan microscope, comprising a beam combining arrangement (1) used to combine laser light beams (19) of different wavelengths, wherein said arrangement combines individual beam combining devices (2), characterized in that the beam combining devices (2) are arranged in a row or according to groups parallel to each other and are respectively configured in order to inject a laser light beam (19) having a wavelength of a defined wavelength range.
Abstract:
A method for operating a preferably confocal laser scanning microscope, whereby the laser system (1) includes at least one solid laser or a diode laser. The inventive method avoids undesirable falsification of image data and is characterized in that the scanning process or acquisition of data is synchronized with a substantially continuous intensity emission phase of said laser system (1). The laser system (1) and the data acquisition system (3) are synchronized via a control unit (2).
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 scanning microscope (1) has an incoupling apparatus (31) with which light (33) other than the light (17) proceeding from the sample (7) is coupled into the detection beam path and conveyed to the detector (21). A closure apparatus automatically closes off the incoupling apparatus from the outside, in largely light-tight fashion, when the light guide (37) guiding the other light to the incoupling apparatus is removed. An independent claim is also included for confocal scanning microscope.
Abstract:
The device has a detector array (4) disposed downstream of a prism (2). The detector array has a light-insensitive region and a light-sensitive region. The prism and the detector array are matched to each other such that a selectable wavelength component of a light beam (1) hits the light-insensitive region (6) and a remaining wavelength component of the light beam hits the light-sensitive region. An independent claim is also included for a method for suppressing excitation lines in a detection light beam of a microscope.
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.
Abstract:
In a method for scanning microscopy a specimen, that contains at least one fluorescent dye, is illuminated with illuminating light. The detection light proceeding from scan points of the specimen is detected with a spectral detector that generates spectral data for each scan point. An amplitude value is determined from the spectral data for each fluorescent dye and transferred to a processing module.
