    摘要: A method for wavelength-selective and high spatial resolving fluorescence microscopy. In a specimen fluorescence emitters are repeatedly excited and specimen frames are produced with a microscope. The fluorescence emitters are excited to emit fluorescence radiation such that at least a sub-set is isolated in each frame and the positions of the isolated fluorescence emitters are localized with a localization precision exceeding the optical resolution and a high-resolution complete image is produced. The imaging beam path of the microscope has a spectrally selective element which, during production of the frames, generates a spectrally-dependent rotational asymmetric point-spread function, such that images of isolated fluorescence emitters have a rotational asymmetry which depends on a wavelength at which the isolated fluorescence emitters fluoresce, and the images of the isolated fluorescence emitters are analysed with respect to rotational asymmetry and an indication of the wavelength of the isolated fluorescence emitters is derived therefrom.

    摘要: The present invention relates to a digital microscope that includes an objective lens for enlarged optical imaging of a sample in an image plane. An image with an optical resolution may be represented in the image plane by means of the objective lens. The microscope also includes an image sensor for converting the image, depicted on the image sensor by the objective lens, into an electrical signal. The image sensor includes a matrix of pixels by means of which a maximum image resolution of the image sensor is determined, which is finer than the optical resolution of the objective lens. The objective lens has a maximum magnification factor of at most 40. The optical resolution of the objective lens is defined as a minimum distance between two structures that are distinguishable in the image. The maximum image resolution of the image sensor is defined by a pixel pitch. A quotient of the minimum distance between two structures that are distinguishable in the image and the pixel pitch defines a scanning factor that is at least 5.

    摘要: The invention relates to a device and a method for imaging a sample (2) arranged in an object plane (1). Such a device comprises an optical relay system (3) which images an area of the sample (2) from the object plane (1) into an intermediate image plane (4). Here, the object plane (1) and the intermediate image plane (4) with an optical axis (5) of the relay system (3) include an angle different from 90°. The optical relay system (3) is composed of several lenses. The device also comprises an optical imaging system (6) with an objective, the optical axis (7) of which lies perpendicularly on the intermediate image plane (4) and which is focused on the intermediate image plane (4), with the result that the object plane (1) can be imaged undistorted onto a detector (8). Finally, the device also comprises an illumination apparatus (10) for illuminating the sample (2) with a light sheet (11), wherein the light sheet (11) lies essentially in the object plane (1) and defines an illumination direction, and wherein the normal of the object plane (1) defines a detection direction.In such a device, the object plane (1) with the optical axis (5) of the relay system (3) includes an angle, the value of which is smaller than the aperture angle of an object-side detection aperture cone (12) of the relay system (3), and the object plane (1) lies at least partially within the object-side detection aperture cone (12). The intermediate image plane (4) with the optical axis (5) of the relay system (3) also includes an angle, the value of which is smaller than the aperture angle of an intermediate image-side detection aperture cone (13) of the relay system (3), and the intermediate image plane (4) lies at least partially within the intermediate image-side detection aperture cone (13).

    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.
