Preparation Before Surgery
Adjusting the eyebase and eyepoint Interpupillary distance scale
2. Focus on the test object ¸¸Set the maximum magnification. ¸¸Focus the microscope. ¸¸Set the minimum magnification.
3. Adjusting the diopter settings ¸¸Adjust the diopter setting for each eye in turn, until the
image is seen in sharp focus.
75 65 55
Setting wheel The interpupillary distance and preferred degree of contact with the eyepieces vary from user to user. Prepare the microscope for surgery using a user table. Adjusting the eyebase ¸¸Set the eyelenses of the eyepieces to "0" or select the
required diopter value.
¸¸Set the magnification changer to step 10. ¸¸Look into the eyepieces and adjust the tubes with the
setting wheel or by hand (in the case of binocular tubes without a setting wheel) until a circular field of view is visible.
¸¸Set the maximum magnification. ¸¸Focus the microscope again. ¸¸Set the minimum magnification. ¸¸Inspect the diopter settings, readjusting them if necessary
so that both images are sharp.
4. Checking parfocality ¸¸Zoom through the whole range, observing the test
object. The image sharpness must remain constant at all magnifications. If it does not, then repeat points 2 to 4 of this procedure.
Show/switch footswitch type See page 22.
Adjusting the parfocality Rotary ring for adjusting the diopter settings
Adjusting the diopter settings Adjust the diopter 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. ¸¸Set the maximum brightness. ¸¸Set the minimum magnification. ¸¸Shift the microscope until the test object is visible in the center of the field of view and reasonably sharp.
