Setting the colposcope
Notes on adjustment
– It is recommended to provide the interpupillary distance as well as the re-
fraction values for the different users to adjust the colposcope more quick-
ly and to preset the values in the scope of the preparation.
– Do not wear multifocal or varifocal glasses during adjustment or during
the operation of the colposcope.
Such glasses make a proper diopter adjustment ring setting impossible
and result in unsatisfactory imaging.
– Optimum image clarity in the eyepieces and at the optical port for docu-
mentation equipment (photo, video) can only be achieved through careful
focusing and precisely adjusting the binocular tube.
Adjusting the binocular tube
Adjusting the interpupillary
distance
• Position the colposcope at a right angle to an even surface with a suitable
pattern for focusing.
• Adjust the distance of the eyepieces at the binocular tube to your interpu-
pillary distance so that the two eyepiece images (object and edge of visual
field) merge into one.
Adjusting the eyepieces The following procedure must be performed separately for each eyepiece in
the order described.
• Set the colposcope to minimum magnification.
• Set the diopter adjustment ring at the eyepiece to zero position.
• Look through the eyepiece and move the colposcope body to focus the
image.
• Set the colposcope to maximum magnification and adjust the fine focus-
ing system until the image is sharply defined.
• Then reset the microscope to minimum magnification 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.
