Abstract: According to a method for autofocusing on a microscopic sample, measurement light having a local structure is generated. The measurement light is coupled into the microscope beam path, whereby the measurement light is incident on, and reflected by, the sample. The measurement light reflected by the sample is output from the microscope beam path and split among a plurality of component beam paths which pass over optical paths of different lengths to image the reflected measurement light, whereby a plurality of measurement images assigned to different focus positions on the microscope beam path are obtained. At least the measurement image which comes closest to an ideal image of the local structure of the measurement light is selected. Depending on the focus position assigned to the selected measurement image, a focus position to be used on the microscope beam path for the purpose of microscopic imaging of the sample is set.

The system also includes an easy to use patient interface with a one-piece contact element, a computer program product for methods of the incision guidance and sequentially operating referencing methods with patient interfaces containing markings.

Abstract: A system for therapy of the eye by treating tissue with therapeutic radiation using nonlinear interaction. A laser device is provided, which delivers the therapeutic radiation. The therapeutic radiation is focussed by a focussing device in an image field, and xy scanners and z scanners shift the focus laterally and longitudinally within a treatment volume. The therapeutic radiation is either a second short pulse radiation or a first short pulse radiation, each of which have a spectral centroid within a wavelength range defined by the short pulse properties. The system is particularly corrected with regard to longitudinal chromatic aberrations and lateral chromatic aberrations such that the spectral characteristic curves of the two aberrations each have a local extreme within the wavelength ranges, and a certain tolerance within the wavelength ranges is not exceeded, therefore the characteristic curves are very shallow.

Abstract: Disclosed is a beam splitter assembly for being arranged in a non-collimated part of a beam path of a microscope with a first plate, which is tilted with respect to an optical axis by a tilting angle, and with a second plate, which is tilted with respect to the optical axis by a tilting angle, wherein the first plate and/or the second plate serve(s) for coupling radiation in and/or out. The beam splitter assembly can include a wedge angle of the first plate, a wedge angle of the second plate and the tilting angle of the second plate, which are coordinated with one another in such a way that an astigmatism on the optical axis and a linear field dependence of the astigmatism in an object field are corrected. Also disclosed are a method for dimensioning a beam splitter assembly and a microscope.

The invention also relates to a method for processing a tissue of an eye by a therapeutic laser beam of an ophthalmological laser therapy device.
