Definitions
- the present invention relates to a tube for a microscope.
- the invention relates to a tube for a microscope with a lens that defines an objective beam path, the tube defines a tube beam path, a binocular provided on the tube defines an eyepiece beam path, a deflecting element is provided in the tube beam path, a deflecting mirror from the position of a user seen behind the lens beam path is provided.
- the European patent application EP-0 844 505 discloses a tube which can be changed in the angular position.
- the tube consists of an insight and a mirror, which is arranged in such a way that it rotates by half the angle when the eyepiece insight is pivoted by a certain angle.
- the optical structure of the tube itself is complicated, requires considerable adjustment and is not inexpensive.
- German patent application DE 103 00 455.6 discloses a tube for adaptation to a microscope.
- An adaptation interface, a rotatably arranged operator interface, a beam deflection device and a rotatably arranged beam deflection unit are provided.
- a light steel coming from the adaptation interface is deflected in the direction of the rotatably arranged beam deflection unit.
- a rotation of the operator interface is forcibly coupled with a rotation of the rotatably arranged beam deflection unit.

- Beam guiding means and an operator interface Beam guiding means and an operator interface.
- a beam of light coming from the adaptation interface can be deflected with the beam deflection unit in such a way that its optical axis runs at least in certain areas essentially in a predetermined plane and can be guided to the operator interface by the further beam guiding means.
- a relative movement of the tube housing together with the further beam guiding means and the operator interface to the microscope is provided in a direction parallel to the predetermined plane.
- the German patent application DE 35 08 306 A1 discloses a microscope cube.
- the tube allows the attachment of additional devices.
- a first concave deflecting mirror and a second deflecting mirror are provided, which couple the light from the observation beam path into the eyepieces.
- the second is closer to the eyepieces.
- the second deflection mirror is arranged along the optical axis of the observation beam path. The deflection of the beam path is relatively complicated and not easy to adjust.
- the present invention is therefore based on the object of a tube with which the viewing angle can be changed or which has a fixed ergonomic viewing angle. It is also important to ensure that the binocular is arranged on the tube in such a way that ergonomic operation of the actuating elements of the microscope is possible. In addition, the number of reflections in the tube should not exceed two.
- the only tube lens system is arranged in front of the deflection element in the region of a connection element to the microscope.
- the binocular has two eyepieces, with an intermediate image being created in each of the eyepieces.
- the distance from a lens apex of the single tube lens system to the intermediate image is not greater than 1.25 times the focal length of the tube lens system.
- the first embodiment has a pivotable binocular.
- the pivoting movement of the binocular is forcibly coupled to the pivoting movement of the deflecting mirror.
- the positive coupling between the deflecting mirror and the binocular is designed such that when the binocular is pivoted by the value ⁇ , the deflecting mirror pivots by an angle ⁇ / 2.
- the deflecting mirror and the binocular are fixed and unchangeable.
- the angle ⁇ of the binocular between the horizontal and the eyepiece beam path is preferably fixed between 7.5 ° and 20.0 °. This setting is made in the factory and can no longer be changed by the user.
- FIG. 1 a side view of a microscope onto which the tube according to the invention can be placed;
- FIG. 2 shows a schematic representation of the structure of the tube according to the invention, the exemplary embodiment of a rotatable deflecting mirror being shown here; 3 shows an exploded perspective view of the tube according to the invention for a fixed embodiment;
- Fig. 4 shows a cross section through the tube with an assembled
- Fig. 6 is a plan view of the holding element. 1 to 6 the same or similar components are identified by the same reference numerals.
- the microscope 1 shows a side view of a microscope 1 onto which the tube 30 according to the invention (not shown here) can be placed.
- the microscope 1 comprises a microscope stand 2.
- the microscope 1 stands on a base 10.
- a revolver 3 is provided on the microscope stand 2, which carries at least one objective 4.
- the objective 4 can be pivoted into a working position by the turret 3.
- the objective 4 has or defines an optical axis 5 which is perpendicular to the microscope stage 6 in the working position of the objective 4.
- An object 7 to be examined is placed on the microscope stage 6.
- a connection element 8 for the tube 30 is provided on the top of the stand.
- FIG. 2 shows a schematic representation of the structure of the tube 30 according to the invention, the exemplary embodiment of a rotatable deflection mirror being shown here.
- the tube 30 is also shown as
- Ergonomic tube refers to the fact that it can adjust to the different ergonomic requirements of different users or can be prefabricated accordingly.
- the tube 30 can be placed on the various upright tripods from Leica through the connection element 8.
- the light enters the tube 30 from the objective 4 with an infinite image width through the connection element 8.
- the light propagates in the optical axis 5 or in the objective beam path.
- the tube lens system 11 defines a tube beam path 16.
- the deflecting mirror 18 is arranged such that in no position of the deflecting mirror 18 the angle between the incident beam 16a and the emerging beam 16b does not exceed 90 °.
- the distance a 3 between the optical deflecting element 15 and the deflecting mirror 18 is selected such that a minimum viewing angle of 7.5 ° measured from the horizontal H can be achieved without the emerging beam 16b being shadowed on the optical deflecting element 16.
- the deflection element 16 is preferably designed as a prism.
- the pivotable deflecting mirror 18 shown in this exemplary embodiment sits with its mirror surfaces in the middle of a pivot axis D about which the entire binocular 20 with the two eyepieces 13 is pivoted. Due to the forced coupling, the pivotable deflecting mirror 18 is pivoted simultaneously at half the angular velocity of the binocular 20.
- the eye relief of the two eyepieces 13 is adjusted according to the “boiling pot principle”.
- the distance from the last lens vertex of the compact tube lens system 11 to the intermediate image 12 must be kept as short as possible for optical reasons (to avoid vignetting). The distance should not be greater than 1.25 times the focal length of the tube lens system 11.
