4.10 Focusing
• Adjust the zoom to maximum (2.0) on the magnification
unit.
• Approach the object with the colposcope until the
image is sharp.
• If the zoom level is changed, the pre-adjusted degree
of sharpness is still maintained.
4.10.1 Fine focusing
The optional fine focusing allows for sensitive and precise
focusing in a 17 mm range. Fine focusing is necessary in
order to focus accurately while zooming in.
• Replace the mounted lens with the appropriate lens
for fine focusing (simple mounting via the screw mount
on the colposcope head. Secure with the intermediate
screwed ring).
• Conduct focusing as described above.
• Adjust focus by use of the lateral adjusting disk.
4.11 Exchanging the binocular tube
The tube's focal distance of 160 mm allows for comforta-
ble and fatigue-proof observation of the object with both
eyes. Working is made easier due to the exceptionally
large exit pupil and an increased stereo base of 24 mm.
Please hold the lens tube with one hand while loosening
the screw. Otherwise, the lens tube could drop.
• Loosen the screw on top of the lens tube and remove
the tube from the colposcope head.
• Make sure that the gudgeons and grooves of the dove
tail fixation engage and the tubes lie flat.
• Tighten the screw again.
• Check for secure fit.
