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.

Surgical microscope system and method

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

In a microscope with an objective, a variable magnification system and an autofocus arrangement, the autofocus arrangement produces a projection beam path for the projection of an autofocus marking onto an observation object, and an imaging beam path which passes through an objective, for imaging on a detector the autofocus marking projected onto the observation object. The projection beam path and/or the imaging beam path then passes through the variable magnification system outside its optical axis.

Microscope with an autofocus arrangement having a variable magnification

The invention relates to a high-precision autofocusing arrangement for a stereomicroscope wherein a bar-shaped marking is projected via a cylinder optic on an object. The imaged bar-shaped marking is at least in one dimension less or equal to the resolution of the viewing beam path. A region of the objective not used optically is selected for projection as the pass-through pupil.
