Using the microscope

8.1

Adjusting interpupillary distance

Hold the right and left eyepiece tube with both hands
and adjust the interpupillary distance by moving the
two parts 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 interpupilla-
ry distance is too small. (Fig. 36)
8.2

Focusing

Put the sample to be observed on the stage plate
and focus the sample using the focusing knobs ①. If
necessary adjust the height of the microscope head
along the vertical stand. Remember to lock the lock
screw ② after aligning the height of the microscope.
(Fig. 37)
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.
8.3.1

SZ-A1

Grab the knobs ③ both hands and, while holding the
left knob, turn the right knob. The tension increases
or decreases depending on the direction of rotation
of the right knob. (Fig. 38)
8.3.2

SZ-A6

Turn the adjusting ring ④ clockwise until the desired
tension is achieved.
Turning it counterclockwise will cause the tension to
drop, resulting in a loss of focus. (Fig. 39)
