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.

Microscopy system, microscopy method, and a method of treating an aneurysm

A surgical microscope has an illuminating arrangement for illuminating light in an operating region to be examined with the surgical microscope. The arrangement contains a high-power light source which includes an intensity adjusting device. The device makes possible an adjustment of the intensity of the illuminating light, which is guided to the object region, between a maximum value and a minimum value. The microscope has a control unit for the illuminating arrangement which includes an operator-controlled module via which the illuminating arrangement can be activated and controlled. For adjusting the intensity of the illuminating light guided to the operating region, the control unit coacts with the adjustable filter unit. A signal generator outputs a warning signal when an intensity of the illuminating light is adjusted via the operator-controlled module which exceeds the safety limit value stored in a memory.

A stereo-examination system including an objective arrangement configured to receive an object-side beam bundle emanating from the object plane and to convert the object-side beam bundle into an image-side beam bundle and a selection arrangement configured to select at least one pair of partial beam bundles from the image side beam bundle. The system also includes an image transmission apparatus configured to generate stereoscopic images of an object positionable in the object plane from the at least one pair of partial beam bundles and an illumination arrangement. The illumination arrangement includes a light source, a beam coupler to superpose a beam cross-section of the illumination beam with the image-side beam bundle, and a field of a plurality of state-changing elements. The elements are selectively switchable between a first state directed and a second state in which light of the illumination beam is and is not directed to the object plane.

Microscopy system, microscopy method and a method of treating an aneurysm

A microscopy system comprises a microscopy optics and a stand supporting the microscopy optics. The stand has a plurality of hinges, of which a first group comprises a position detecting sensor for sensing a hinge position and a second group comprising an actuator for the change of the hinge position. In an automatic control mode, the actuators are controlled in dependence of signals of the position detecting sensors.

Microscopy system and method

An examination system and a corresponding examination method, comprise: Arranging a tissue region in a vicinity of an object plane of a microscope and generating an optical image of the tissue region, receiving tissue data from a measuring head separate from the microscope, discriminating the tissue data into at least two data categories and displaying markings in the optical image of the tissue region in dependence of the discriminated data category and a relative position between a component of the microscope and the measuring head.

Examination system and examination method

A tooth is irradiated with light (), in particular with visible light for identifying tooth-colored tooth filling residues () of the tooth. The light with which the irradiation procedure is effected includes at least one wavelength component that is absorbed or scattered by the tooth filling material differently from the tooth material in such a way that the tooth filling material differs from the tooth material in respect of its brightness or in respect of its color. Thus the identification of tooth filling residues () can be effected in such a way that the dentist can recognise the tooth filling residues () with the naked eye, or possibly with the assistance of simple technical aids such as for example a color filter.

Method for identifying tooth-colored tooth filling residues

An optical observation apparatus includes: an optical system which produces an image of an object being observed and a video device () for recording the image and producing an image signal. The video device () includes a first memory () for temporarily storing the image signal, a second memory () in data communication () with the first memory (), and a control device () in communication (A,B) with both memories () for controlling the storage procedure in the first memory and data transfer from the first to the second memory. The control device () controls the storage procedure and the data transfer so that overwriting of such data already stored for a given period of time in the first memory () is effected and that transfer of the content of the first memory () to the second memory () takes place as a reaction to a trigger signal.
