  • Patent number: 11340477
    Abstract: An ophthalmic lens has a changeable corrective effect, which automatically changes over a predetermined period of time. Further, the ophthalmic lens provides a gradually increasing undercorrection of the far point of the eye over the course of a day, which brings about a deceleration in the axial length growth of the eyeball. In addition, a method for automatically adapting a corrective effect, a pair of spectacles, and a use of an ophthalmic lens are disclosed.

  • Publication number: 20190041621
    Abstract: A method for the optical detection of an illuminated specimen, wherein the illuminating light impinges in a spatially structured manner in at least one plane on the specimen and several images of the specimen are acquired by a detector in different positions of the structure on the specimen. An optical sectional image and/or an image with enhanced resolution is then calculated. The method includes generating a diffraction pattern in the direction of the specimen in or near the pupil of the objective lens or in a plane conjugate to the pupil. A phase plate with regions of varying phase delays is dedicated to the diffraction pattern in or near the pupil of the objective lens or in a plane conjugate to said pupil, and different phase angles of the illuminating light are set.

  • Patent number: 9927226
    Abstract: A method and a configuration for the depth-resolved optical detection of a specimen, in which a specimen or a part of the specimen is scanned by means of preferably linear illumination. The illumination of the specimen is periodically structured in the focus in at least one spatial direction. Light coming from the specimen is detected and images of the specimen are generated. At least one optical sectional image and/or one image with enhanced resolution is calculated through the specimen. Images are repeatedly acquired and sectional images are repeatedly blended while changing the orientation of the linear illumination relative to the specimen and/or spatial intervals between lines exposed to detection light from the illuminated specimen region are generated for the line-by-line non-descanned detection on an area detector or a camera and/or, during a scan, light is further deflected upstream of the detector through the line in the direction of the scan of the specimen.

  • Publication number: 20170367878
    Abstract: The invention relates to a device for measuring an optical penetration that is triggered in a tissue underneath the tissue surface by means of therapeutic laser radiation which a laser-surgical device concentrates in a treatment focus located in said tissue. The inventive device is provided with a detection beam path comprising a lens system which couples radiation emanating from the tissue underneath the tissue surface into the detection beam path. A detector device generating a detection signal which indicates the spatial dimension and/or position of the optical penetration in the tissue is arranged downstream of the detection beam path.

  • Patent number: 9697605
    Abstract: A method for the three-dimensional imaging of a sample in which image information from different depth planes of the sample is stored in a spatially resolved manner, and the three-dimensional image of the sample is subsequently reconstructed from this stored image information is provided. A reference structure is applied to the illumination light, at least one fluorescing reference object is positioned next to or in the sample, images of the reference structure of the illumination light, of the reference object are recorded from at least one detection direction and evaluated. The light sheet is brought into an optimal position based on the results and image information of the reference object and of the sample from a plurality of detection directions is stored. Transformation operators are obtained on the basis of the stored image information and the reconstruction of the three-dimensional image of the is based on these transformation operators.

  • Patent number: 9404867
    Abstract: A luminescence microscopy method includes a sample being used, which comprises a certain substance, wherein the certain substance can be converted repeatedly from a first state, in which it can be excited into emitting luminescence radiation, into a second state, in which it cannot be excited into emitting luminescence radiation. The substance present in the sample can be brought into the first state by irradiating switch radiation. The certain substance can be excited into emitting luminescence radiation by irradiating excitation radiation. The sample emitting luminescence radiation can be displayed. A high-resolution selection of sample regions extending perpendicularly to a sample surface is carried out by irradiating either the switch radiation or the excitation radiation as structured illumination of the sample. A high-resolution selection of the sample surface is carried out by irradiating the switch radiation and/or the excitation radiation as TIRF illumination of the sample.

  • Patent number: 9348127
    Abstract: In structured illumination microscopy, the multiple recording of images with different phase positions of the structuring requires a high stability in the optical arrangement and sample throughout the entire measuring process. Also, the structuring must be projected into the sample in a highly homogeneous manner. The current invention optimizes recording of individual images in order to achieve the best possible resolution in the result image even in problematic samples. An optimization of this kind can be carried out in different ways, for example, by determining an optimal adjustment for at least one illumination parameter or recording parameter or by pulsed illumination such that an excitation from a triplet state of the fluorescent dye to a higher triplet state is reduced, or by illuminating the sample with depletion light for depopulating a triplet state of the fluorescent dye, which reduces bleaching.
