Your Transmitted-light Microscope
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.
Electric LED illumination?
The microscope is equipped with modern LED
lighting (a light-emitting diode) that illuminates
the specimen from below. (By the way, the thing
you want to observe with the microscope is
known as the object or specimen.)
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
magnification.
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
magnification (objective 4x).
Note:
Before you change the objective setting,
always move the microscope stage (Fig. 1, 11)
to its lowest position. This way, you can avoid
causing any damage!
Now, insert the 10x

into the Barlow lens
f
(Fig. 1, 3). Make sure
that the Barlow lens is
D
placed all the way into
the eyepiece 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 correctly, the following basic rules are to be
observed:
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.
