Abstract: The ophthalmologic microscope comprises a first component including a base and a stage, a second component including a pivotal arm and a microscope device, and a third component including a pivotal arm and a light source. The various components are mutually pivotal at a hinge. An electronically controlled brake and a position sensor are incorporated into the hinge. The brake controller of the microscope is adapted to interrupt a manual mutual displacement of the components in response to a signal from the position sensor in order to assist the user in properly aligning the components.

Abstract: In the device and method, the angle of incidence of slit light onto an eye to be examined is determined from its Purkinje reflection recorded in an image by measuring the offset from the reflection to the apex of the image of the cornea. In another embodiment, Purkinje reflections of light sources arranged around the optical axis of the microscope are correlated with a reference pattern of radial stripes in order to determine the offset between the optical axis and the apex of the eye.

Abstract: An ophthalmic microscope assembly has an ophthalmic microscope with a camera, a voice recorder with speech-to-text conversion, a measurement unit for carrying out measurements, and a report generator for generating reports. Depending on the physical input, such as the voice data from the voice recorder, the image data from the camera, the data measured by the measurement unit, as well as the current operating settings of the microscope, report generator automatically generates a report. Depending on the same data, a guide automatically generates guidance to the user and/or performs measurements and takes images. A microphone is placed below the ocular or on the frame of a display of the microscope.

Abstract: The ophthalmic workstation comprises a table having a top surface, a base unit mounted to the table, a microscope, and a headrest. The base unit includes an X-displacement stage, a Z-displacement stage, and a platform mounted to the X-displacement stage and the Z-displacement stage. The microscope is mounted to the platform. The table comprises an opening in its top surface. An embedded section of the base unit is located, at least in part, in this recess or opening. The headrest is mounted to a headrest section of the base unit, which projects laterally over an edge of the table.

Abstract: An ophthalmologic device includes a microscope, an illumination system, a camera positioned to record an image through the microscope, and a storage device. When examining an eye, the camera is operated to continuously record a series of images. The images are stored in the storage device, each one with attributed imaging parameters describing the recording conditions of the image. When the examiner wants to retrieve images taking under examining conditions similar to the one presently used, the device is able to automatically retrieve the closest matches from the storage device. This allows to record, in the background, a large number of images documenting an eye's history and to retrieve them efficiently.

Abstract: In a method for testing a disposable on a medical examination appliance, more particularly on a tonometer, wherein the medical examination appliance comprises a disposable holding apparatus, on which a disposable is held and, in particular, able to be brought into contact with a patient's eye for an applanation tonometry measurement, and which comprises a detection device, by means of which a physical property of the disposable can be measured, a measured value of the physical property of the disposable is ascertained by means of the detection device.

Abstract: A Michelson-interferometer which has two reference arms and a short coherence length is used for the method and apparatus for measurement of geometric values on transparent or diffuse objects (19). The basic optical delay times of the reference arms (11, 12) are chosen in such a manner that they result in an optical delay time difference corresponding to a layer thickness, as a geometric value. The at least two reference arm beams (33a, 35a) are passed to a single rotating path-length variation element (23), with a mutual spatial offset angle (dw). A delay-time change, which is dependent on the rotation angle, of the reference arm beams is produced as a function of a rotation angle caused by rotation, in order to allow a delay-time change caused by the path-length variation element (23) to be applied successively to the basic optical delay times in the reference arms (11, 12).
