4.15 Measuring scale
Measuring scale
Via a small turning knob beneath the lens, a true-to-scale dimension scale can be faded into the field of the illumination light path.
This documentation display enables the measurement of objects regardless of the selected magnification. The scale will be dis-
played in both the 3D picture and on all camera pictures, and if required, it can be faded out at any time.
• To fade in the scale, turn the knob by 45° in clockwise direction.
• Via a 45° rotation in counterclockwise direction, the scale can be faded out from the path of illumination.
The following measures have to be observed: - Distance 2 mm, - Line width 0.75 mm.
Please note that these specifications are only correct for the following combination: Measuring scale for 300 mm lenses, 300 mm
lenses with fine focusing, or wide-angle eyepieces 16x.

4.12 Pivoting H.A.S.I. filter
The pivoting H.A.S.I. filter gives a more contrasting and
clearer view of the mucosa.
• Turn the function knob by 90° in clockwise direction to
swing in the filter.
• By turning the knob by 90° in counterclockwise direc-
tion, the filter is removed from the optical beam path of
the colposcope.
