Preparation for Operation
The distance between both pupils and the desired contact with
the eyepieces are adjusted individually.
You can prepare the surgical microscope before the operation
using the data from a user table.
Regulate the interpupillary distance
➩Turn the eyelenses on the eyepieces to "0" or set the dioptric
settings, if known.
➩Set the magnification changer to step 10.
➩Look through the eyepieces and adjust the tubes by hand
(for binocular tubes without drive knobs) or using the drive
knob (1) until you see a concentrically circular image field.
Set the interpupillary distance and
eyepoint
Adjust for parfocality
1
Adjusting the dioptric settings
Adjust the dioptric settings accurately for each eye separately;
only this method will ensure that the image will stay in
focus throughout the entire zoom range (parfocal).
1. Prepare the microscope
➩Switch on the microscope at the control unit and place a flat
test object such as a piece of paper beneath the objective.
➩Engage the highest brightness.
➩Engage the lowest magnification.
➩Displace the microscope so that the test object is visible in
the center of the field of view.
2. Focus on the test object
➩Engage the highest magnification.
➩Bring the test object into focus.
➩Engage the lowest magnification.
3. Adjust the dioptric settings
➩Adjust the dioptric settings for each eye in turn (2), so that
the image is seen in sharp focus.
➩Engage the highest magnification.
➩Refocus using motor-driven focusing.
➩Engage the lowest magnification.
➩Inspect the dioptric settings, readjusting them if necessary
so that both images are sharp.
4. Inspect the parfocality
➩Zoom through the whole range, observing the test object.
The image sharpness must remain constant at all magnifica-
tions. If it does not, then repeat points 2 to 4 of this proce-
dure.
