    摘要: The invention is directed to an optical system for a fundus camera for reflection-free opthalmoscopy having a beam path with refractive and reflective optical elements which are used substantially in common for illumination and observation or recording. An imaging mirror system substantially comprising a plurality of reflecting optical elements in the form of mirrors and is provided for illuminating and imaging the fundus. At least one optical element, for example, mirror, is formed as a freeform mirror with an imaging, reflecting freeform surface. The optical elements are arranged in a housing in a precisely defined position and attitude relative to one another in such a way that an imaging of the reflecting surfaces of the optical elements on the image of the imaged retina is prevented within a wide diopter range of the patient's eye to be examined.

    摘要: A stripe pattern of known distance is imaged on the ocular fundus by the imaging unit for ophthalmological devices. This makes it possible to carry out absolute measurements of distances and objects at the ocular fundus with knowledge of the initial values serving as a basis. The imaging unit for ophthalmological devices, particularly fundus cameras, according to the invention comprises a device for generating and imaging any, but a known, stripe pattern or line pattern on the retina of an eye to be examined, a camera for recording the stripe pattern or line pattern on the retina, and an evaluating unit for determining the distances on the retina. The imaging unit is constructed in such a way that the stripe pattern or line pattern to be imaged is coupled into the beam path between the ophthalmological device and the eye to be examined. The use of an imaging unit of this kind as an accessory to ophthalmological devices also expands the possibilities for its use in measurements at the ocular fundus. Although the proposed solution is particularly suited to fundus cameras, it can also be used for other ophthalmological device.

    摘要: 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 illumination and irradiation unit can also be used as an independent unit or as an auxiliary unit for various ophthalmologic devices, such as slit lamps, fundus cameras, laser scanners, ophthalmoscopes and operating microscope systems.

    摘要: A camera adapter for optical devices, in particular microscopes. The present solution is directed to a camera adapter which makes it possible to connect any video cameras and photographic cameras to an existing image out-coupling system, e.g., the beam splitter of a microscope. The adapter can also be used for stereo microscopes and in particular for ophthalmic 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, 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. 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.
