Use of the microscope

8.1

Adjust interpupillary distance

Hold the right and left eyepiece tube with both han-
ds and adjust the interpupillary distance by moving
the two parts (Fig. 16) until one circle of light can be
seen. If two circles appear, the interpupillary distance
is too big, and if two overlapped circles appear, the
interpupillary distance is too small.
8.2

Focus

Put the sample to be observed on the stage plate
and focus the sample using the focusing knobs of the
stand ①. (Fig. 17)
8.3

Adjusting the tension of the focus knob

• This adjustment allows to increase or decre-
ase the tension of the knob by avoiding an
involuntary descent of the microscope body
under its own weight. Adjust the tension just
above the point where the focus is stable.
Grab the focus knobs with both hands and, holding
left knob rotate the right one in the direction shown
in Fig. 18 to increase the tension. Tension increases
or decreases according the sense of rotation of the
right focus knob.
