Objective
Eyepiece version
in a transmitted-light microscope
The depolarizer is required for minimization of
disturbances by the polarization equipment and
facilitates work with birefringent objects
2.2.2 Monitor version
An LCD shutter (
"3D illumination shutter"
) is
positioned close to the aperture diaphragm and
is used to open or close half a side of the beam
path.
With the monitor version, the LCD shutter is
controlled via the "
3MCU II"
unit.
The centroid of the illumination beam path is
switched in such a way that the object is
illuminated alternately from a right and a left
stereo angle.
The camera and the monitor shutters are
controlled at the same pulse rate, i.e. each eye
only sees the image on its own side
.

In the monitor version, allocation is made via
the display of the half images in two
perpendicular polarization directions which can
be allocated to the eyes by polarizing glasses.
A flicker-free display of the stereo image
composed of the right and left images is made
possible by an appropriately high pulse rate.
When the illuminator - eye allocation is
changed, a pseudostereo effect is created
(height-changed images).
Resolution, contrast and depth can be
optimized with relation to the object via the
aperture diaphragm.
