Abstract: An applicator for an ophthalmologic treatment or diagnostic device, wherein a laser beam and an illumination beam are directed at the eye and light reflected from the eye is fed to an examining beam path. A reflective surface is provided for the reflection of the illumination beam and comprises an optical aperture for the laser beam.

Abstract: A homogeneously illuminating ophthalmic instrument includes an illumination device having a source of illumination, a homogenizing unit and a projection device, at least one organic or inorganic source of radiation with spectrally selective emission being used as a source of illumination. The illumination generated in this way enables correspondingly adapted visual and/or digital observation, recording or display of the examined regions of the eye by a visualizing unit.

Abstract: A camera adapter for optical devices, in particular microscopes. The present solution includes a camera adapter which enables any video cameras and photographic cameras to connect to an existing image out-coupling system, e.g., the beam splitter of a microscope. The adapter can also be used for stereo microscopes. The camera adapter is arranged between the image out-coupling element and the camera. Its housing has two connection pieces. The microscope-side connection piece has a quick-change device and the camera-side connection piece has a filter thread. The technical solution provides a camera adapter for connecting digital cameras to a microscope. By using intermediate rings, the camera adapter is suitable for different cameras and facilitates exchange of cameras. The camera can be positioned in such a way that the observer can view the object through the eyepiece as well as on the camera monitor without substantially changing his/her sitting position.

Abstract: The present invention is directed to a method and an arrangement for automatic detection, documentation and reproduction of the adjusted magnification. The magnification steps are read off at the rotational axis of the magnification changer, monitored by a control unit and stored for reproducing the magnification setting. For this purpose, a cylinder is arranged on the rotational axis of the magnification changer, this cylinder having a quantity of magnets with radially oriented magnetic fields which divide the cylinder into segments. An arrangement of sensors which are fixedly connected to the housing is located opposite from these magnets for detection of their magnetic fields. The quantity and arrangement of sensors correspond to the quantity and arrangement of magnets. The solution supports a comprehensive computer-assisted control of the instruments and offers the possibility of defined standardized sequences.

Abstract: The invention relates to an assembly for generating a variable illumination for diagnosis and therapy, in particular of the human eye. The illumination and irradiation unit consists of an illumination source that emits light, elements for generating special illumination patterns and/or profiles, in addition to elements for coupling the light from the light source into the parallel beam path of the viewing system of the ophthalmologic device. The inventive solution generates different marks, patterns and profiles and can also be used both for diagnosis and therapy in ophthalmology. The illumination unit is therefore suitable for different ophthalmologic devices. It can also be configured as a modular unit for retroactive assembly in the parallel beam path of an ophthalmologic device. To achieve this, a beam divider that is already present in the respective ophthalmologic device is used.

The technical solution provides a camera adapter for connecting digital cameras, preferably having a monitor at the back of the housing, to a microscope, particularly an ophthalmic microscope. By using intermediate rings, the camera adapter is suitable for different cameras and facilitates exchange of cameras.

Abstract: Microperimetry and examinations of the front and back of the eye are made possible by the ophthalmologic examination instrument. The ophthalmologic examination instrument with at least one illumination arrangement for generating temporally and spatially variable light marks and/or luminous fields has an input unit for adjusting the illumination conditions, a signaling device for reporting the detectability and/or undetectability of the light marks, an output unit, and a control unit. In the method, a light mark for fixating the patient's eye and a movable light mark which is variable with respect to position, shape, brightness and/or color is projected in sequence on the back of the eye. Conclusions can be made about the vision of the patient from the detectability of the light marks on the part of the patient. Based on its varied possibilities for producing and manipulating light marks and/or luminous fields, the suggested solution offers an extremely broad applicability in eye examinations.

Abstract: A subassembly for generating an optically active slit with a changeable slit width s, preferably for slit lamps, with two slit jaws which are displaceable relative to one another at a straight-line guide and between which the slit is formed, wherein one of two guide paths is allocated to each slit jaw. In a subassembly for generating an optically active slit, the guide paths are formed at portions of a guide rail which project out freely in the displacement directions of the slit jaws from a clamping position which is fixed with respect to the frame. The guide rail can accordingly expand without hindrance in the displacement direction under the influence of temperature without the parallelism of the slit being affected thereby.

Abstract: Ophthalmic device, such as a slit lamp or a visual acuity testing device or a combination of these devices, for variable illumination of the patient's eye with illumination fields of different geometries, wherein the illumination of the patient's eye is generated by means of chip components which are controllable electronically with respect to their light transparency, light reflection or light emission and which are illuminated by reflected light or transmitted light or are self-illuminating.
