摘要:
A microscopy system and method allow observing a fluorescent substance accumulated in a tissue. The tissue can be observed at a same time both with visible light and with fluorescent light. It is possible to observe a series of previously recorded fluorescent light images in superposition with the visible light images. An end of the series of images may be automatically determined. A thermal protective filter may be inserted into a beam path of an illuminating system at such automatically determined end of the series. Further, the fluorescent light image may be analyzed for identifying a coherent fluorescent portion thereof. A representation of a periphery line of the coherent portion may be generated, and depths profile data may be obtained only from the coherent portion. An illuminating light beam for exciting the fluorescence may be modulated for improving a contrast of fluorescent images.

An ophthalmologic surgical work station has a microscope and a foot switch corresponding thereto. The microscope is connected to the foot switch via a console. The microscope and the foot switch are coarsely prepositioned and a change of the relative position between the microscope and the foot switch with respect to each other is only possible via a fine positioning.

摘要:
An optical imaging system, for example, for a surgical microscope (100) has a beam deflecting unit in order to cast light rays out of an object region (112) into an image plane (104) with an optical beam path. An optical phase plate (107) is mounted in the optical beam path. In the optical imaging system, a unit for generating a geometric image of the image plane is provided, for example, an ocular unit (105). The optical phase plate (107) is arranged on the end of the objective lens (101) facing away from the object or is arranged in a region of the optical imaging system in which the beam path is parallel.

An optical observation apparatus has an optical image channel for viewing optical field-of-view images, a processing unit to generate a first electronic insertion image via a first electronic image channel, and a data insertion image projector for generating an optical insertion image from the first electronic insertion image and inserting that image into the optical field-of-view image. An acquisition device acquires the optical field-of-view image without the optical insertion image inserted by the data insertion image projector. A second electronic image channel has a superimposition module, that superimposes the electronic field-of-view image with an electronic insertion image and provides the superimposed images via the second electronic image channel. The processing unit generates a second electronic insertion image, provides available display data elements, and makes it possible to assemble the electronic insertion images and assign them to different electronic image channels.

摘要:
A surgical microscope (100) for ophthalmology includes a measuring unit (110) for determining at least one characteristic value of a patient eye (104). The measuring unit (110) is connected to a computer unit (120) which calculates a model of the patient eye (104) based on the determined characteristic variables. The surgical microscope also includes a display device for displaying the calculated model of the patient eye (104) or characteristic variables that are derived from the calculated model.
