Definitions
- the invention relates to a device for reflecting at least one stereoscopic observation beam path from a microscope, for example a stereo surgical microscope.
- a stereomicroscopic device in various variants, which consists of at least two stereomicroscopes M- ⁇ and M 2 with a common object plane, which allows simultaneous observation of the operating field by two or more people.
- a combination of reflectors ensures that the axes of the individual observation beam paths coincide between the objective and the object.
- the fact that such microscopes have not established themselves on the market is due to the fact that, according to FIG. 1 of this publication, the divider prism below the main objectives O- and O 2 of the microscopes M 1 and M 2 is arranged and there leads to astigmatism in the convergent beam path, which cannot be corrected due to the rotation of the microscope M 2 around M.
- the overall height is sufficiently small.
- DE-A1-195 41 420 describes a microscope in which the illumination device can be arranged in at least two positions relative to the main microscope.
- a mirroring for an assistant microscope is thus described, which is arranged rotatably about the axis of the main microscope and between the objective and this main microscope. In the system described, this leads to a large, ergonomically unfavorable overall height as well as to vignetting and reflections which are disturbing for the observer.
- US-A1-2001 / 0010592 describes a microscope in which a horizontal, two-channel zoom system is proposed to reduce the overall height.
- Assistant microscope arranged below the main lens. This provides an interface from which the assistant's microscope can optionally be removed.
- each microscope requires its own main objective, which may have to be coupled to one another electromechanically.
- the usability is also limited because rotation is not possible. Since the beam splitter of the assistant's microscope is also penetrated by the illumination beam path, reflections are extremely difficult to remove. This beam splitter is penetrated divergent by the observation beam path and thus leads to annoying vignetting. With this arrangement of
- the beam splitter also has to accept an astigmatism that depends on the relative orientation of the assistant's microscope to the main microscope.
- the invention is therefore based on the object of providing a device which has an optically and mechanically continuously rotatable mirroring of Allows at least one stereoscopic observation beam path for an assistant microscope while avoiding all of the disadvantages mentioned above.
- a beam splitter for mirroring the stereoscopic assistant's observation beam paths is arranged between the main objective and the zoom of the main microscope, which together with the assistant microscope can be rotated continuously around the optical axis of the main microscope and can therefore be used optically in any rotational position is.
- Continuously rotatable is understood to mean a rotation about the optical axis of the main objective, which enables any rotation angle around the axis to be infinitely variable and / or in steps.
- the arrangement of the beam splitter is combined according to the invention with a zoom, the axis of which deviates from the optical axis of the main microscope.
- This zoom consists of two identical optical systems, which are preferably perpendicular to the optical axis of the main lens. There is therefore a zoom in each stereoscopic partial beam path.
- the beam splitter can effect a geometric or physical beam splitting and can be designed as a splitter cube, splitter plate or pellicle or even consist of an LCD element.
- the main observation beam paths and the assistant observation Beam paths the common main lens, which additionally advantageously means that no separate lens with an electromechanical coupling to the main lens is necessary for the assistant microscope.
- the assistant's microscope can be removed from the microscope via a mechanical separation point.
- the assistant's microscope can be removed from the main microscope with or without a beam splitter.
- the assistant's microscope can contain optical components (round and / or plane optics) in the area between the beam splitter and the deflecting element, which make it possible to change this distance between the beam splitter and deflecting element.
- optical image reversal elements for example Dove prisms - find their place in the area between the beam splitter and the deflection element.
- the shared main lens can be designed for a fixed or variable focal length.
- a variable focal length of the main lens it makes sense to guide the illumination through the main lens, that is to say to arrange it between the main lens and the divider prism. This automatically ensures that the illuminated field is always assigned to the object field in the correct position and size.
- the overall height is disadvantageously increased. To avoid this, it is advisable to use the "lens with lighting" described in the German patent application with the official file number: 102 35 706.4.
- This main lens which is shared by the main and assistant observation beam paths and the illuminating beam path, is separated into a lens part for observation and a second lens part for lighting, the lens part for lighting being removed from the main lens and at an angle to the optical axis of the main lens is arranged.
- the lens with illumination described above can optionally be rotated around the optical axis of the main lens.
- Fig. 1 the overall structure of a device according to the invention for mirroring in side view
- Fig. 2 a detailed view of the device shown in Fig.1 with a rotatable beam splitter in supervision.
- FIG. 1 shows a main microscope 1 with a surgeon as the main observer H with a main objective 2 with a vertical optical axis 4, an object 3 and an assistant microscope 8 for an assistant A.
- An illuminating beam path 12a originating from a light source 16 and having an axis 12 is projected onto an object 3 - for example a patient - via a deflection element 13.
- the object 3 is imaged by stereoscopic main observation beam paths 4a, b via a main objective 2, a beam splitter 7 and a further deflection element 5 into a horizontally lying zoom 6.
- the beam splitter 7 divides the main observation beam path 4a into two sub-beam paths: The one sub-beam path continues to transmit the beam splitter 7 as the main observation beam path 4a. The other partial beam path is reflected by the beam splitter 7 from the main observation beam path 4a as an assistant observation beam path 9a.
- This assistant observation beam path 9a is guided via a further deflection element 10 into a binocular tube with eyepieces (not shown in the figure for the sake of simplicity). Due to its arrangement, this deflecting element 10 enables tilting and thus an angle-variable deflection by the amount ⁇ of the observation beams 9a, b for the assistant A.
- the binocular tube can be arranged rotatably about an optical axis 9, which lies between the assistant's observation beam paths 9a and 9b, of the assistant's microscope 8 and thus enable rotation by the angle ⁇ of the assistant's observation beam paths 9a, b.
- the assistant microscope 8 can be detachable from the main microscope 1 at a mechanical separation point 11, for example.
- a distance variation 15 indicates the possibility of varying the distance between the beam splitter 7 and the deflection element 10.
- the deflection element 10 relative to the Beam splitter 7 about an axis 14 which lies between the two assistant observation beam paths 9a, b in order to rotate an angle ⁇ .
- FIG. 2 shows a rotation ⁇ of the beam splitter 7, which takes place continuously around the optical axis 4 of the main objective 2.
- the main observation beam paths 4a, b and the assistant observation beam paths 9a, b are also shown.
- the outline of the main objective 2 is visible as a projection into the plane of the beam splitter 7. According to the invention, the beam splitter 7 is rotated together with the assistant microscope 8 (not shown in this figure).
