Abstract
The invention concerns an apparatus for illuminating a viewing field by means of two light sources. The beam paths of the two light sources are guided through a combining flexible light guide, a common flexible light guide, and a separating flexible light guide splitter. One of the two beam paths is directed to the microscope as principal illumination, and the other beam is directed to a handpiece. In addition, at least one of the two light sources can be configured as an interchangeable unit having two individual light sources.
Claims26
An apparatus for illuminating a viewing field comprising:
- a microscope having a light output;
- a handpiece;
- a first light source adapted to emit a first beam of light along a first beam path;
- a second light source adapted to emit a second beam of light along a second beam path;
- a combining flexible light guide which is adapted to collimate the first and second beams into a unified beam;
- a common flexible light guide adapted to guide the unified beam;
- and
- a separating flexible light guide splitter which is adapted to receive and divide the unified beam into at least two beams a first of which is directed to the light output of the microscope and a second of which is directed to the handpiece.
