Avoid touching optical elements and keep out of contact with dust, water or other
contaminating agents, as they could stain, or damage the lens surface and affect the quality of
the image.
Remove and handle all components of the stereomicroscope with extreme care.
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 base in an upright position on a flat, stable and clean surface.
b. Loosen the head locking screw, and place the head in the head holder with extreme care.
c. Re-tighten the head locking 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 stages. One is frosted glass for the observation of microscopic
specimens slides, or thin, or transparent samples such as leaves, insect wings, and so forth. The
black/white stage is used to study opaque objects, or for dissection. The best contrast of a sample
would depend on the side of the stage chosen.
Warning:
ONLY use transmitted light with the frosted glass stage. HEAT GENERATED BY THE
TRANSMITTED LIGHT MAY MELT OR DAMAGE THE BLACK/WHITE STAGE. SUCH DAMAGE IS
NOT COVERED BY THE WARRANTEE.
1. Changing the Stage
a. Loosen the locking set screw situated on the front, and remove the stage plate.
