Zero-degree assistant's device for a microscope
View Patent ↗A zero-degree assistant's device for a microscope has a tube carrier ( 2 ) for the principal observer's tube, an interface ( 5 ) for the microscope body, an assistant's module ( 6 ), pivotable about an axis ( 4 ), having an interface ( 7 ) for an assistant's tube, and having a retaining device ( 8, 12 ) for releasing and immobilizing the assistant's module ( 6 ), the tube carrier ( 2 ) for the principal observer's tube being mounted tiltably about a rotation axis ( 10 ) in such a way that tilting of the tube carrier ( 2 ) for the principal observer's tube into a tilted position makes possible unrestricted pivoting of the assistant's module ( 6 ).
1. A zero-degree assistant's device for a microscope, the device comprising:
a microscope body interface ( 5 ) for mounting the zero-degree assistant's device on a microscope body;
a tube carrier ( 2 ) for a principal observer's tube, the tube carrier ( 2 ) being mounted on the microscope body interface ( 5 ) for rotation about a tilt axis ( 10 ) relative to the microscope body interface ( 5 ) between a working position and an adjustment position; and
an assistant's module ( 6 ) including an interface ( 7 ) for an assistant's tube, the assistant's module being pivotable about a pivot axis ( 4 ) relative to the microscope body interface ( 5 ) through at least 180 degrees when the tube carrier ( 2 ) is tilted about the tilt axis ( 10 ) to the adjustment position.
2. The zero-degree assistant's device according to claim 1 , further comprising a retaining device ( 8 ) fixedly connected to the tube carrier ( 2 ) and having a retaining screw ( 9 . 1 ) thereon for selectively engaging the microscope body interface ( 5 ).
3. The zero-degree assistant's device according to claim 2 , wherein tilting of the tube carrier ( 2 ) is enabled by disengaging the retaining screw ( 9 . 1 ) from the microscope body interface ( 5 ).
4. The zero-degree assistant's device according to claim 2 , wherein the assistant's module ( 6 ) is pivotable about the pivot axis ( 4 ) through 180 degrees, and the assistant's module ( 6 ) can be immobilized by the retaining device ( 8 ) and retaining screw ( 9 . 1 ) at a zero-degree position and at a 180-degree position.
5. The zero-degree assistant's device according to claim 1 , further comprising a locking mechanism ( 12 ) that disengages the assistant's module ( 6 ) for pivoting only upon tilting of the tube carrier ( 2 ) beyond a predetermined tilt angle, and otherwise locks the assistant's module ( 6 ) against pivoting.
6. The zero-degree assistant's device according to claim 5 , wherein the locking mechanism ( 12 ) locks the assistant's module ( 6 ) to the microscope body interface ( 5 ).
7. The zero-degree assistant's device according to claim 5 , wherein the assistant's module ( 6 ) is pivotable about the pivot axis ( 4 ) through 180 degrees, and the assistant's module ( 6 ) can be immobilized by the locking mechanism ( 12 ) at a zero-degree position and at a 180-degree position.
8. The zero-degree assistant's device according to claim 1 , wherein the assistant's module ( 6 ) is arranged beneath the tube carrier ( 2 ); and the tube carrier ( 2 ) is tiltable in an upward direction to the adjustment position.
9. The zero-degree assistant's device according to claim 1 , wherein the tube carrier ( 2 ) can be tilted about the tilt axis ( 10 ) through an angle that is selected from the group of angles of consisting of 20, 25, 30, 35, 40, and 45 degrees.
10. The zero-degree assistant's device according to claim 1 , further comprising an accessory interface ( 20 ) for mounting documentation accessories, wherein the accessory interface ( 20 ) is located outside a pivot range of the assistant's module ( 6 ).
11. The zero-degree assistant's device according to claim 1 , further comprising:
a documentation part ( 27 ) connected to the microscope body interface ( 5 ), the documentation part ( 27 ) including an accessory interface ( 20 ) for a documentation accessory,
wherein the assistant's module ( 6 ) further includes a pair of optical beam paths ( 21 , 22 ), and at least a portion of the pair of optical beam paths is coupled out from the assistant's module ( 6 ) and conveyed to the accessory interface ( 20 ).
12. The zero-degree assistant's device according to claim 11 , wherein the interface ( 7 ) for the assistant's tube is configured for receiving a binocular tube, and the assistant's module ( 6 ) includes a pair of beam splitters ( 23 ) one in each optical path ( 21 , 22 ) for coupling out the pair of optical paths ( 21 , 22 ).
13. The zero-degree assistant's device according to claim 12 , wherein the assistant's module ( 6 ) further includes additional optical elements ( 24 , 25 ) after each beam splitter ( 23 ) for conveying an outcoupled beam path, and the documentation part ( 27 ) includes a front-end interface optical system ( 26 ) with which an outcoupled beam path is alignable for conveying the outcoupled beam path to the accessory interface ( 20 ).
14. The zero-degree assistant's device according to claim 11 , wherein the accessory interface ( 20 ) is located outside a pivot range of the assistant's module ( 6 ).
