Abstract: A device for outcoupling a portion of the radiation of an observation beam path of a binocular eyepiece for documentation or co-observation that is freely selectable at any time. For the outcoupling, a rotatable supporting unit, the axis of rotation of which is parallel to the axes of the observation beam paths, is arranged in the housing having the binocular eyepiece. Three optical elements are arranged on this supporting unit such that an outer and the middle optical element and, after rotation of the supporting unit, the middle and the other outer optical element are each located in one of the observation beam paths. Here, the two outer optical elements have a beam-splitting effect and outcouple a portion of the observation radiation into a common documentation beam path.

Abstract: An intraocular lens system for implantation in an eye is provided. The intraocular lens system includes a ciliary body implant having a passive ciliary signal element, the ciliary body implant being implantable in the eye such that the ciliary signal element provides a ciliary signal in response to a movement of the ciliary muscle of the eye. The intraocular lens system also includes an intraocular lens having a sensor element for receiving the ciliary signal. The ciliary body implant and the intraocular lens are formed separately from each other and the intraocular system is configured to control a refractive effect of the intraocular lens that is dependent on the ciliary signal received from the sensor element.

Abstract: Methods and apparatuses for fundus imaging are presented that use sequential selective illumination patterns to suppress unwanted reflections, scattering and haze from various optical components of a fundus-viewing instrument. This is particularly the case with those unwanted reflections produced by the objective lens contained within said instrument.

Abstract: A fundus camera for the recording of high-resolution color images of the fundus of non-dark-adapted eyes, and without the use of a mydriatic. The fundus camera has a strip-shaped pupil division, and includes a coherent or incoherent illumination source with illumination optics, a deflection mirror and an ophthalmoscope lens for illuminating the eye, detection optics and a detector for detecting the light reflected by the eye, and a control and evaluation unit. The deflection mirror has a strip shape, and the spatially resolving detector can be activated and read out in sectors. The control and evaluation unit connects the data read out in sectors in the form of a bright image from the detector and produce a resulting fundus image. The fundus camera records images of the fundus when the eyes are not dark-adapted for this purpose and no mydriatic has been used.

Abstract: Imaging optics for optical devices, with which reflections of the illumination light, which is guided through the same optical elements as the observation light, are kept from reaching the observation pupil of the imaging beam path. The non-reflective imaging optics include at least two refractive optical elements, which are utilized for illumination as well as observation. The at least two refractive optical elements are designed approximately wedge-shaped and are tilted at a random azimuth angle of at least 5° and/or are positioned off-center in the beam path to block out the single reflections of the illumination, occurring at the optical system surfaces, for the observation. The imaging optics are for optical devices, particularly in ophthalmology thought the invention is applicable to other ophthalmological devices as well as to optical devices outside of this field.

Abstract: A method is used to wind a toroidal core with a wire obtained from a magazine having a ring shape. The method includes winding the wire onto the toroidal core in a fixed winding plane, rotating the toroidal core during winding, the rotating being about an axis that is perpendicular to a plane of the ring shape of the magazine, and holding the toroidal core using a gripper that moves with the toroidal core during winding.

Abstract: An apparatus for the laser processing of workpieces with shortened processing time. Two laser units that can be simultaneously operated are directed towards each other. Workpieces, for example printed circuit boards, are moved between the two laser units such that the two sides of the workpieces are simultaneously processed. As a result the processing time is considerably shortened.

Abstract: A method and arrangement for calibrating a laser processing machine for processing workpieces. The present invention ensures a fast and reproducible method and arrangement for calibrating a laser processing machine by measuring a position of a predetermined test pattern on a test plate while taking into account any imaging errors caused by the deflection unit.

Abstract: A workpiece, designed as a printed circuit board for example, can be moved by means of a transport device under a laser unit in such a way that a region to be machined of the workpiece passes into the deflecting region of the laser beam. The workpiece is set between clamping jaws to a vertical position in which the laser beam is focused exactly on that surface of the workpiece which is to be machined. As a result, the machining accuracy can be considerably increased.
