Abstract
Lighting device for a microscope comprising at least one observation beam path, in particular a surgical microscope, with an illumination system (3, 4, 5, 28, 29) and a deflection device (8; 48, 49) for deflecting light emitted from the illumination system onto an object to be observed, in particular an eye to be operated on, the deflection device providing an illumination of the object under various illumination angles with regard to the at least one observation beam path, wherein the deflection device comprises two deflection elements (16, 17) at least partly provided as physical beam splitters.
Claims14
A lighting device for a surgical microscope for illuminating an observed object at various illumination angles relative to an observation beam path of the microscope, the lighting device comprising:
- an illumination system for emitting light;
- and
- a deflection device for deflecting the light emitted by the illumination system onto the object, wherein the deflection device includes two deflection elements each being at least in part a physical beam splitter.
A microscope for observing an object, the microscope comprising:
- a main objective;
- a magnifying system downstream of the main objective;
- and
- a lighting device including an illumination system for emitting light and a deflection device for deflecting the light emitted by the illumination system onto the object, wherein the deflection device includes two deflection elements each being at least in part a physical beam splitter;
- whereby the lighting device is operable to illuminate the object at a plurality of illumination angles relative to an observation beam path of the stereomicroscope
A microscope for observing an object, the microscope comprising:
- a main objective;
- a magnifying system downstream of the main objective;
- a lighting device for illuminating the object, the lighting device including an illumination system for emitting light and a deflection device for deflecting the light emitted by the illumination system onto the object, wherein the deflection device includes a first deflection element being at least in part a physical beam splitter and a second deflection element that includes a reflective surface;
- and
- at least one glass block insertible into an observation beam path of the microscope.
