ENGLISH
Congratulations on your Celestron microscope purchase. Your
new microscope is a precision optical instrument, made of high
quality materials to ensure durability and long life. It is designed
to give you a lifetime of enjoyment with a minimal amount of
maintenance.
Before attempting to use your microscope, please read through
the instructions to familiarize yourself with the functions and
operations to maximize your experience. Refer to the microscope
diagrams to locate the parts discussed in this manual.
The microscope provides high powers from 40x to 600x. It
is ideally suited for examining specimen slides of yeasts and
molds, cultures, plant and animal parts, fibers, bacteria, etc.
You can also examine small and thin objects at low powers such
as coins, rocks, insects, various materials, etc. You can also
explore the exciting microscopic world by creating your own
specimen slides. An excellent book to get you started, which
describes various projects and activities along with techniques,
is “The World of the Microscope” by Usborne.
The final section of this manual provides simple care and
maintenance tips for you to follow to ensure that your
microscope provides you with years of quality performance,
usage, and enjoyment.

MAGNIFICATION TABLE
Use the following table to determine the magnification
for the different eyepiece/objective lens combination of your
microscope.
1. Take the Styrofoam container out of the carton.
2. Remove the tape from the Styrofoam container holding the
various parts in place.
3. Carefully remove the microscope and other parts from the
container and set them on a table, desk, or other
flat surface.
4. Remove the plastic bag covering the microscope.
5. Remove the plastic cap from the zoom eyepiece
Fig. 1 (1).
6. Install the batteries for the bottom illuminator in the base
Fig. 1 (11) of the microscope which uses two AA batteries
(user supplied). See Figure , showing the battery 3a
compartment closed at the back of the microscope. Figure
3 shows the batteries being installed in the compartment b
(see the inside of the battery compartment door to locate
where the positive (+) and negative (-) ends of the batteries
go). Pull out on the door to open it while holding the base
firmly and push firmly to close it after the batteries are
installed.
You are now ready to use your microscope for looking at
specimen slides or small objects through the zoom eyepiece!
SETTING UP YOUR MICROSCOPE
VIEWING A SPECIMEN
Carefully place a specimen slide under the stage clips Fig.
1 (8) and center the specimen directly over the hole in the
center of the stage Fig. 1 (7). Figure 4 shows the stage area a
with the hole in the center and Figure 4 shows a specimen b
slide centered over the hole in the stage. It will take some
experimenting to place slides or objects in the center of the
stage as the image you see is upside down and reversed
but after some usage you will have an easy time centering.
Read the sections below on Focusing, Changing Power, and
Illumination before proceeding.
You are now ready to focus and view the specimen, but first
you must take some precautions so you do not damage a
specimen slide or valuable object. When using the higher
powers while you are focusing, make sure that the objective
lens does not hit the slide or object being viewed.

FOCUSING & CHANGING POWER (MAGNIFICATION)
Now that the specimen slide (or object) is placed directly
under the objective lens, use the focus knob Fig. 1 (9) to
focus on the specimen. Note that for very small objects, you
should set them on the clear slide with a recessed hold in
the center.
1. Always start with the lowest power (4x objective lens) and
have the zoom eyepiece at the 10x position, all the way
counterclockwise (when you are facing the microscope from
the front) until it stops, so that the total power is 40x – this is
the most useful power for solid objects.
2. For slightly higher power, you can rotate the knurled ring
on the zoom eyepiece (see Figure 5) clockwise to obtain
powers of 40x to 80x (or anywhere in between) as you
continue rotating to the 20x eyepiece position. Note that
you will have to refocus whenever you rotate the eyepiece
to obtain a sharp focus.
3. For much higher powers, you will have to rotate the
nosepiece Fig. 1 (5) to change the objective lens to 15x
(provides total power of 150x to 300x depending on what
position you have the zoom eyepiece in or 30x provides total
power of 300x to 600x). You rotate the nosepiece by holding
the microscope above the nosepiece with one hand and
rotate the nosepiece with the other hand until it clicks at the
position. Be cautious not to let the objective lens touch the
specimen slide or object when changing to higher powers
– you should turn the focus knob first to lower the stage to
a low position. Note the power range of the objective lens
you are using is shown on the nosepiece after it clicks into
position.
4. At the highest powers, your views will be greatly magnified
but somewhat darker. The most enjoyable views can be
at the lower powers which have a wider field of view and
brighter illumination.
ILLUMINATION
To get the sharpest and best views, the illumination (lighting)
will have to be adjusted.
1. The top illuminator Fig. 1 (3) is used only for solid objects
(not specimen slides) so that light shines down onto the
object. Push the button on the top of the illuminator to turn
it on/off. After some usage, you can determine the best way
of adjusting the light to provide the most pleasant views.
2. The bottom illuminator Fig. 1 ( is used for specimen 10)
slides which shine up through the hole in the stage through
the slide. You can see a close up of the illuminator in Figure
6a below. The illuminator is turned on by rotating it so the
light goes up through the hole. You turn off the illuminator
by rotating it down so that the mirror is on the upper part
(the mirror is not useful with this microscope since you
have the much better electric illuminator).
3. The light from the bottom illuminator can be increased or
decreased by rotating it with very slight movements.
4. The bottom illumination may be too bright with some
specimen slides. Included with your microscope is a light
diffuser which reduces the brightness and glare somewhat
and can make the views sharper with a higher contrast
level. In Figure the diffuser is the small black piece. The 6a
diffuser fits over the bulb area by press fitting it on. Figure
6b shows what the illuminator looks like with the light
diffuser in place. It will take experimenting to get this right.
