S7 / OPMI PROergo Preparations for use
Adjusting the surgical microscope
Notes on adjustment
– To permit fast setup of the microscope, it is advisable to store the pupillary
distances and prescriptions of the different users so that they can be easily
preset during system preparation.
– Do not wear any bifocal or progressive lenses for the adjustment
procedure and subsequent work with the microscope.
Lenses of this kind make correct diopter setting impossible and result in
unsatisfactory imaging.
– Optimum image clarity in the eyepieces and at the optical port for
documentation equipment (photo, video) can only be achieved through
careful focusing and precisely adjusting the binocular tube.
Adjusting the binocular tube
Adjusting the
pupillary distance
• Position the microscope vertically above a flat object, e.g. a piece of paper
with writing on.
• Bring the eyepieces on the binocular tube to eye distance, so that the two
eyepiece images (the object and the periphery of the field of view) merge
to produce a single image.
Adjusting the eyepieces The following procedure must be performed separately for each eyepiece in
the order described.
• Set to the smallest magnification on the microscope.
• Set the diopter adjustment ring at the eyepiece to zero position.
• Look through the eyepiece and move the microscope to focus the image.
• Set the microscope to the highest magnification and correct the fine
focusing until the image is defined sharply.
• Now set to the smallest magnification once again without changing the
working distance.
• Set the diopter adjustment ring at the eyepiece to its maximum value (plus
direction).
• Look through the eyepiece and slowly turn the diopter adjustment ring to
the minus direction until the image is sharply defined.
