How do I use my microscope?
Before you assemble your microscope, make
sure that the table, desk or whatever surface
that you want to place it on is stable, and does
not wobble.
How do I operate the electric LED
illumination?
The batteries supplied should be inserted into
the battery compartment (15) located in the
base plate before use.
Remove the battery compartment cover by
pressing lightly on the cover clip. Insert the
batteries (3x AA) into the holder.
There are two lights on the microscope. They do
not use light bulbs, but rather light-emitting di-
odes (LED). The first lamp shines onto the speci-
men from below and the second from above.
(The thing that you want to observe with the
microscope is called the object or specimen, by
the way.) You can use each lamp on its own, or
both of them together. There is a selection knob
for this (Fig. 1, 14). It has three numbers: I, II
and III.
If you select the ...
I, the light only comes from below (transmit-
ted light).
II, the light only comes from above (reflected
light).
III, both lamps shine light on the specimen.
For transparent objects (transmitted-light ob-
jects), number I is best. In order to observe firm,
non-transparent objects (direct-light objects),
select number II. For semi-transparent objects,
it is best to select number III.
It is not recommended to use number III for
transmitted-light objects on slides, since the
light may cause reflections on the surface of the
slide, which will disturb your observation.
When do I use the color filters?
The color filters (Fig. 1, 17) are located below
the microscope stage (Fig. 1, 11). They help you
when you are observing very bright or clear
specimens. Here, you can choose from various
colors. This helps you better recognize the com-
ponents of colorless or transparent objects (e.g.
grains of starch, protozoa).
