How do I adjust my microscope correctly?
First, loosen the screw (Fig. 1, 7) and turn the
microscope head (Fig. 1, 6) into a comfortable
viewing position.
Each observation starts with the lowest magni-
fication.
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) un-
til it clicks into place at the lowest magnification
(objective 4x).
Note:
Before you change the objective setting, always
move the microscope stage (Fig. 1, 11) to its low-
est position. This way, you can avoid causing any
damage!
Now, insert the 10x
B/C
Fig. 2
eyepiece (Fig. 1, 1) into
f
the Barlow lens (Fig. 1,
3). Make sure that the
D
Barlow lens is placed
all the way into the eye-
piece supports (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 cor-
rectly, the following basic rules are to be ob-
served:
Start with a simple observation at the lowest
magnification. This way, it is easier to position
the object in the middle (centering) and make
the image sharp (focusing).
The higher the magnification, the more light you
will require for a good image quality.
Now place the prepared
2) specimen (Fig. 6, 20)
directly under the objec-
tive on the microscope
I
stage (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 eyepiece
(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 magnification
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 magnification can be increased to almost
double.
If you would like an even higher level of magni-
fication, insert the 16x eyepiece (Fig. 1, 2) and
turn the objective nosepiece (Fig. 1, 8) to a high-
er setting (10x or 40x).
Important tip:
The highest magnification is not always the best
for every specimen!
Note:
Each time the magnification changes (eyepiece
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 contact and become
damaged!
Which light for which specimen?
With this unit, a reflected light and transmitted
light microscope, you can observe transparent,
semi-transparent as well as non-transparent
objects. The image of the given object of obser-
vation 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 components,
stones, coins, etc.) with this microscope, the
light falls on the object that is being observed.
