Abstract
A stereomicroscope includes a first beam path and a second beam path, wherein in the first beam path a first telescope system is provided and in the second beam path a second telescope system is provided. An observation unit comprising a first and a second observation unit is also provided. At least one optical element of the first telescope system compared to at least one corresponding optical element of the second telescope system has a different optically effective diameter. Between the first telescope system and the second telescope system and the first and the second observation units a prism group is provided which can be moved in the beam path of the first telescope system with the larger diameter of the entrance pupil.
Claims14
A telescopic stereomicroscope comprising:
- a first beam path;
- a second beam path;
- a first telescope system disposed in the first beam path and having at least one first optical element;
- a second telescope system disposed in the second beam path and having at least one second optical element corresponding to the at least one first optical element, wherein the at least one first optical element has a larger optically effective diameter than the corresponding at least one second optical element;
- a binocular observation unit configured for first and second eyes of a user including a first observation unit corresponding to the first eye of the user and a second observation unit corresponding to the second eye of the user;
- and
- a prism group disposed between the first and second telescope systems and the binocular observation unit, the prism group being movable into an operating position in the first and second beam paths so as to supply the first beam path to the first and second observation units and removable out of the operating position.
A telescopic stereomicroscope comprising:
- a first beam path;
- a second beam path;
- a first telescope system disposed in the first beam path;
- a second telescope system disposed in the second beam path, wherein at least one magnification of the first telescope system is greater than a magnification of the second telescopes system;
- a binocular observation unit configured for first and second eyes of a user including a first observation unit corresponding to the first eye of the user and a second observation unit corresponding to the second eye of the user;
- and
- a prism group disposed between the first and second telescope systems and the binocular observation unit, the prism group being movable into an operating position in the first and second beam paths so as to supply the first beam path to the first and second observation units and removable out of the operating position.
A telescopic stereomicroscope comprising:
- a first beam path;
- a second beam path;
- a first telescope system disposed in the first beam path and having at least one first optical element;
- a second telescope system disposed in the second beam path and having at least one second optical element corresponding to the at least one first optical element, wherein the at least one first optical element has a larger optically effective diameter than the corresponding at least one second optical element;
- a first observation unit;
- a second observation unit;
- a prism group disposed between the first and second telescope systems and the first and second observation units, the prism group being displaceable in the first beam path to an operated position so as to supply the first beam path to the first and second observation units;
- and
- an adjustment element configured to adjust a magnification of the first and second telescope systems and wherein an operation of the adjustment element brings the prism group into the operated position, if an entrance pupil diameter of the first telescope system is different than an entrance pupil diameter of the second telescope system.
