Use of the microscope

9.1

Adjust interpupillary distance

1. Hold the right and left eyepiece tube with both hands and ad-
just 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.
• If two overlapped circles appear, the interpupillary distance
is too small.
9.2

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)
9.3

Adjusting the tension of the focus knob

• This adjustment allows to increase or decrease the ten-
sion 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.
1. Grab the focus knobs with both hands and, holding left knob
rotate the right one in the direction shown in Fig. 18 to in-
crease the tension.
• Tension increases or decreases according the sense of rota-
tion of the right focus knob.
