Problems solved by technology

[0015] Third, there is a non-negligible risk that, when the two images are superimposed in the mind of the observer, the significantly darker image of the observation channel with small values ​​is suppressed
In principle, this phenomenon can be counteracted with neutral gray filters in observation channels with large numerical apertures, but this in turn nullifies the advantage of brighter images to the greatest extent

Embodiment Construction

[0055] In the figures, unless otherwise stated, the same reference signs are used correspondingly for identically constructed components or identical components.

[0056] If the beam paths are depicted in the drawing, the drawing only shows the factual situation and does not necessarily correspond to the actual beam path, but may be shown differently from the actual beam path in order to be able to explain the described principle.

[0057] Figure 1a The construction of an embodiment of the invention and the light path through the microscope is schematically shown by means of the example of an Abbe-type stereomicroscope 10 . Here, the optical components are shown only schematically as lenses, but can also be more complex optical components, possibly also spatially separated from one another. For the sake of completeness of the illustration of the beam path, the observer's eyes 101 , 201 are also shown in FIG. 1 as optical elements, which are of course not part of the microsco...

Abstract

An optical device for generating images with a three-dimensional effect is disclosed. The device can include a first observation channel, a second observation channel that can be present simultaneously, or alternated in intervals, with the first observation channel. The device can also include a first diaphragm arranged in the first observation channel and having a first aperture. The first aperture can include a first semimajor axis, a first semiminor axis perpendicular to the first semimajor axis such that an extension of the first aperture in a direction of the first semimajor axis is greater than an extension of the first aperture in a direction of the first semiminor axis. Further, the device can include a second diaphragm arranged in the second observation channel and having a second aperture, that can have a second semimajor axis and a second semiminor axis.

Description

technical field [0001] The invention relates to an optical device for producing images with stereoscopic appearance. Background technique [0002] Optical instruments used to produce images with a stereoscopic appearance take advantage of the human brain's ability to see in space, i.e. the human brain thus combines information from individual images with each other and / or analyzes information from individual images with each other The ability of information to leave a three-dimensional overall perception in the mind of the observer. [0003] In other words, two observation channels with different optical properties, such as different optical paths, different light polarizations and / or different light colors, are provided by such an optical device, and the two observation channels combine the observed object's The information composed of two different images seen by the eye is provided to the observer, which in turn leads to a three-dimensional perception of the object. It ...
