8.6 Use of additional lens
1. Screw the desired additional lens on the microscope body.
(Fig. 32)
• The stroke of the focus adapter could not compensate the
different working distances of the several additional lenses.
• In the event that the focus support fails to focus the sample,
the entire body of the microscope must be raised or lowered.
Total magnification used can be calculated as:
Eyepiece magnification * Zoom magnification * Objective lens
magnification.
4. Adjust the diopter compensation ring of the right eyepiece
⑥ (Fig. 30) until the image of the right eyepiece is clear and
sharp. Repeat the procedure for the left eyepiece.
5. Check the focus of the image for the whole zoom range. It
should be perfectly parfocal (focus is maintained during the
change of magnification).
