Definitions

  • the invention relates to an arrangement for the adjustment of binocular fields of view for microscopes and other optical instruments with an eyepiece arranged in each beam path as well as with screens for the purpose of field of view adaptation.
  • the image information from the field of view is also used.
  • the left and the right eye differently visible visual field edges can be very disturbing.
  • a three-dimensional image impression may arise. Since the image impression of both eyes in the brain is usually processed into a uniform image, deviations between the left and the right eye can lead to headaches and impaired vision. Minimizing the problem by narrowing the tolerances of the optical devices to limit the problem to the smallest possible deviations of the visual fields, leads to complex and very expensive devices that still can not completely eliminate the problem.
  • the object of the invention is to develop an arrangement for the adjustment of binocular fields of vision in such a way that a complete transmission Alignment of the image impressions of the left and right eye up to the visual field edges in a relatively simple and thus cost-effective manner is possible.
  • a movable diaphragm designed according to the invention can also be used at the appropriate place in the eyepiece socket of the left and / or the right optical output with known means.
  • the latter variant is always to be understood as an alternative below, when a diaphragm is described in an eyepiece or in the space of an eyepiece.
  • a rotatable, eccentrically placed aperture is sufficient in one view, while in the other view a concentric insertion , fixed iris defines the reference image for the exit with the rotatable iris.
  • the minimum offset must not be zero in this case.
  • the intermediate image or the diaphragm area are in the space of the eyepieces. In order to be able to move an adjustable diaphragm in or in the immediate vicinity of the intermediate image plane, a sufficiently large optical passage is required in this region.
  • eccentrically introduced apertures are used in both eyepieces used, both of which can be rotated with the respective eyepiece for field of view or it is according to the invention an additional - adjustable adjustable - offset of the eccentric aperture used in the Eyepiece provided.
  • each distance of the center of the aperture to the center of the eyepiece can be adjusted. In principle, this could also be achieved with a centrally preset aperture, provided that this is correspondingly displaceable in the intermediate image plane.
  • An advantageous embodiment is that in each of the installation spaces of both eyepieces a diaphragm is eccentrically introduced.
  • the field of view compensation can be carried out by rotation of the eyepieces in a simple manner for a larger range of diverging field of view centers. This also includes the case of the left and right matching insight.
  • Possible design variants for the purpose of moving the diaphragm in the eyepiece are here the arrangements of either two offset by 180 degrees or three offset by 120 adjusting means, which are introduced in the region of the intermediate image plane, so in the wall of the respective Okularbauraumes that these from the outside on the eyepiece are accessible, but preferably not protrude.
  • About the adjustment means located in the interior of the eyepiece aperture can be moved so that it reaches any desired position and is fixed by “clamping", for example, by lightly tightening the screws in position.
  • This embodiment variant of the aperture adjustment proves to the change in position of the aperture by simple rotation of the eyepiece disadvantageous if the adjustment can not be made under observation. But this can be remedied if there is access to the screws in the eyepieces inserted into the optical device.

  • This second, upper ring 9 can then be moved by means of screws 13.
  • two adjusting screws 13 are used at an angle of 120 °, wherein a spring element not shown in detail, preferably offset by 120 "with respect to the adjusting screws 13, is required to move the adjustable aperture 14 in any desired direction

  • other solutions are also possible, for example with other angular distances or with a different number of set screws 13 and / or resilient elements
  • the aperture 14 can be moved in any desired direction, without having to additionally rotate the eyepiece for the field of view, with retracted graticule 7 in the eyepiece, it is still possible by rotation of the entire eyepiece, for example, along a specific structure in the field of view align and subsequently by re-adjustment of the aperture 14 again perform a field of view adjustment, without changing the orientation of the reticle 7.
  • the maximum total of all set screws 13 and resilient elements is not necessarily limited to three components; However, with a larger number of these components, the required effort would be higher without being able to achieve a higher benefit.
