Assembly
All the steps described for the assembly of the stereomicroscope must be undertaken with extreme
care, and without forcing the placement of the distinct parts and elements of the microscope.
A. Place the stereomicroscope, on a flat, stable and clean
surface.
B. For models ST-36/37.
For greater comfort place the head (4) with the
eyepiece (1) to face the opposite direction from the
arm and column (14).
1. Loosen the head holder support screw (Fig. 1)
and turn the head 180º.
2. Tighten the head holder support screw.
Warning
: Before connecting the microscope to an electrical source, always check that
the voltage coincides with that of the stereomicroscope.
Operation
A. Starting Up.
The stereomicroscope comes with two stage plates. One is frosted for the observation of
microscopic specimens slides, or thin, or transparent samples such as leaves or insect wings. The
black and white stage plate is used to study opaque objects, or for dissection. The best contrast of a
sample would depend on the colour of the stage plate chosen.
1. Changing the stage.
a. Loosen the locking set screw (Fig. 2) with the key
provided, and remove stage (9).
b. If glass stage is used, place it with the frosted surface
facing down.
c. Tighten locking set screw
Depending on the stereomicroscope, there are three types of light switch on the base.
MAIN : Turns the entire unit on or off.
I
: Turns incident light on or off. (Top illumination)
T
: Turns transmitted light on or off. (Bottom illumination)
2. Press the main switch to position “I” (7).
3. Press the incident or transmitted illumination switch (16-17), or both at once, to position “I” or “II”,
according to necessities in examining the sample.
