Using the microscope

9.1

Adjusting interpupillary distance

1. Hold the right and left eyepiece tube with both hands and ad-
just the interpupillary distance by moving the two parts until
one circle of light can be seen. (Fig. 6)
• If two circles appear, the interpupillary distance is too big.
• If two overlapped circles appear, the interpupillary distance
is too small.
9.2

Diopter compensation

• This compensation makes possible for people wearing
glasses to adjust the microscope to their eyes and use
the microscope without glasses.
1. Put the zoom down to the lowest magnification ① and focus
the specimen with the focusing knobs ②. (Fig. 7)
2. Put the zoom to the maximum magnification and repeat the
focusing.
3. Return to the lowest magnification: the specimen will be out
of focus.
4. Adjust the diopter compensation ring of the right eyepiece
③ (Fig. 8) until the image of the right eyepiece is clear and
sharp. Repeat the procedure for the left eyepiece ④.
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).
