How do I adjust my microscope correctly?
First, loosen the screw (Fig. 1, 7) and turn the
microscope head (Fig. 1, 6) into a comfort-
able viewing position.
Each observation starts with the lowest mag-
nifi cation.
Adjust the microscope stage (Fig. 1, 11) so
that it goes all the way down to the lowest
position. Then, turn the objective nosepiece
(Fig. 1, 8) until it clicks into place at the lowest
magnifi cation (objective 4x).
Note:
Before you change the objective setting, al-
ways move the microscope stage (Fig. 1, 11)
to its lowest position. This way, you can avoid
causing any damage!
Now, insert the 10x
B/C Fig. 2
eyepiece (Fig. 1, 1)
into the Barlow lens
f
(Fig. 1, 3). Make sure
D
that the Barlow lens
is placed all the way
into the eyepiece sup-
ports (Fig. 1, 5) and is
not pulled out (Fig. 2).
How do I observe the specimen?
After you have assembled the microscope
with the adequate illumination and adjusted it
correctly, the following basic rules are to be
observed:
Start with a simple observation at the lowest
magnifi cation. This way, it is easier to position
the object in the middle (centering) and make
the image sharp (focusing).
The higher the magnifi cation, the more light
you will require for a good image quality.
Now place the pre-
pared specimen (Fig.
2)
6, 20) directly under
the objective on the
microscope
I
(Fig. 3). The object
Fig. 3
should be located di-
rectly over the illumination (Fig. 1, 12).
In the next step, take a look through the eye-
piece (Fig. 1, 1) and carefully turn the focus
knob (Fig. 1, 16) until the image appears clear
and sharp.
Now you can select a higher magnifi cation
by slowly removing the Barlow lens (Fig. 1, 3)
from the eyepiece support (Fig. 1, 5). When
the Barlow lens is almost completely pulled
out, the magnifi cation can be increased to al-
most double.
If you would like an even higher level of mag-
nifi cation, insert the 16x eyepiece (Fig. 1, 2)
and turn the objective nosepiece (Fig. 1, 8) to
a higher setting (10x or 40x).
Important tip:
The highest magnifi cation is not always the
best for every specimen!
Note:
Each time the magnifi cation changes (eye-
piece or objective change, pulling out the
Barlow lens), the image sharpness must be
readjusted with the focus knob (Fig. 1, 16).
When doing this, make sure to be careful. If
you move the microscope stage too quickly,
the objective and the slide could come into
stage contact and become damaged!
Which light for which specimen?
With this unit, a refl ected light and transmitted
light microscope, you can observe transpar-
ent, semi-transparent as well as non-transpar-
ent objects. The image of the given object of
observation is "transported" through the light.
As a result, only the correct light will allow you
to see something!
If you are observing non-transparent (opaque)
objects (e.g. small animals, plant compo-
nents, stones, coins, etc.) with this micro-
scope, the light falls on the object that is be-
ing observed.
