摘要: A localization microscope including an imaging device emitting sample light from a focal plane into an image plane, including an optical-manipulation device for depth-dependent influencing of a point-spread function of the imaging and influencing the point-spread function of the imaging such that a point emitter is imaged in the image plane into an image that is rotationally asymmetrically distorted. A form of the distortion depends on the location of the point emitter with respect to the focal plane and a wavelength of the sample light. The optical manipulation device includes first and second anisotropy elements that anisotropically influence the point spread function to produce rotational asymmetry of the point emitter image. The elements are arranged one behind the other in the imaging direction, with anisotropy axes at an angle to one another. Both elements have differing neutral wavelength at which they do not anisotropically influence the point spread.

摘要: A device and a method for imaging a sample arranged in an object plane. The device includes an optical relay system that images an area of the sample from the object plane into an intermediate image plane. The device may also include an optical imaging system with an objective having an optical axis that lies perpendicularly on the intermediate image plan, and which is focused on the intermediate image plane, with the result that the object plane can be imaged undistorted onto a detector. The device also can include an illumination apparatus for illuminating the sample with a light sheet, wherein the light sheet lies essentially in the object plane and defines an illumination direction, and wherein the normal of the object plane defines a detection direction.

摘要: The invention relates to a microscope having an illumination beam path with wide field illumination of a sample and a first detection beam path having a spatially resolved surface receiver, which is reached by a first part of the detection light coming from the sample via the first detection beam path, or an image divider assembly for a microscope. In order to lengthen the optical path length, at least a second part of the detection light coming from the sample is masked out of the detection beam path and, via deflection means belonging to the detection beam path, is led into a second detection beam path and, preferably via further deflection means, is deflected back in the direction of the detection in such a way that detection light is applied to at least two partial regions beside one another on the surface receiver. At least the second part of the detection light runs in an optical element having an optical density that is increased as compared with the first detection beam path, in order to lengthen the optical path length, and the optical element is designed to be displaceable at an angle, preferably perpendicular, to the optical axis of the first detection beam path in order to adjust the optical path length, and has flat surfaces, at least on the light entry and light exit side thereof; a prism is provided, preferably a glass prism, preferably at least in the second detection beam path after a first beam deflection, for deflection in a direction parallel to the first detection beam path, in order to increase the path length and for reverse deflection.

摘要: A method for high-resolution 3D fluorescence microscopy, wherein fluorescence emitters in a sample are repeatedly excited to emit fluorescence, and still images are produced of the sample by means of a microscope. The microscope has an imaging beam path with an optical resolution and a focal plane, wherein the fluorescence emitters are excited to emit fluorescence in such a manner that at least a subset of the fluorescence emitters is isolated in each still image so that the images of these fluorescence emitters can be separated in the still images within the optical resolution. The positions of the fluorescence emitters are localized in the generated still images, from the images of the isolated fluorescence emitters, with a location accuracy exceeding the optical resolution, and a high-resolution composite image is generated therefrom.

摘要: A microscope including a sample carrier configured to support a sample. Excitation light illuminates the sample via an excitation beam path. Detection light from the sample is guided to detection means via a detection beam path. Through an objective arranged along the optical axis, excitation light is guided in direction of the sample carrier and detection light coming from the sample is guided in direction of the detection means. Beam-splitting means separate excitation light and detection light. Also provided are means for generating a light sheet from excitation light, and means for illuminating the sample with this light sheet. The light sheet lies in a plane at a nonzero angle to the optical axis. The means for illuminating the sample include an optical-deflecting device arranged on or at the sample carrier, which deflects excitation light from the objective into the plane of the light sheet via an optically active surface.

摘要: An arrangement for light sheet microscopy that includes a means for scanning a sample volume with a light sheet, which includes an angle δ≠90° with the optical axis of an objective. The light sheet passes through the entire sample volume in the propagation direction, and the depth of field Sobj of the objective is less than the optical-axis depth T of this sample volume. An optical device, disposed downstream of the objective, increases the depth of field Sobj to a depth of field Seff≧the depth T of this sample volume. The arrangement also includes a means for positioning the sample volume within the region of the depth of field Seff. A spatially resolving optoelectronic area sensor is disposed downstream of the optical device, and hardware and software are provided to generate sample-volume images from the electronic image signals output by the area sensor.
