Assembling Your Microscope
Before you can view through your Celestron microscope, the binocular head assembly must be
attached to the pillar stand (13) and the rubber eyecups must be placed over the eyepieces. To
attach the binocular head assembly:
1. Remove the safety screw from the top of the pillar stand (13).
2. Partially unthread the pillar stand locking bolt (12) located behind the focuser assembly.
3. Place the binocular head assembly onto the pillar stand (13) and slide it half way down the
stand. Be careful not to put too much tension on the cord that goes from the microscope base
to the top light illuminator (10).
4. Rotate the binocular head assembly until the objective turret (5) is directly over the center of
the stage (7).
5. Tighten the pillar stand locking bolt (12) to hold the binocular head assembly in place.
6. Thread the safety screw back onto the top of the pillar stand.
To Attach the Rubber Eyecups:
1. Place the rubber eyecups over the eyepieces with the rubber lips facing up.
2. Push the eyecups down over the tops of the eyepieces.
3. Rotate the eyepieces so that the rubber lips are facing out to the sides.
Your microscope is now ready to view specimens.
Microscope Operation
Powering the illuminator:
Your Celestron microscope has a built-in, 3-setting illuminator powered by 110v AC power. To
power the illuminator:
1. Plug the power cord (8) into a wall outlet.
2. Turn the illuminator switch (9) to the "I" setting to turn on the bottom illuminator bulb.
3. Turn the illuminator switch (9) to the "II" setting to turn on the top illuminator bulb.
4. Turn the illuminator switch (9) to the "III" setting to turn on both the top and bottom
illuminator bulbs.
Viewing a Specimen
To view a specimen:
1. Place the round glass stage plate (7) into the opening above the illuminator. When viewing a
specimen using top lighting only, you may wish to replace the glass stage plate with the
black/white stage plate.
Tip: Specimens of different size and thickness will require different levels of illumination.
Experiment with different lighting for each specimen. When using top lighting, the white side
of the stage plate may wash out fine detail where as the black side will increase contrast but
may make the specimen less bright.
2. Place a specimen slide under the specimen holder clips (6) and center the specimen directly
in the center of the stage.

Focusing:
To achieve the best focus with your microscope, not only can you make adjustments with the
focus adjustment knobs, but you can also adjust the left diopter ring as well as the interpupillary
distance between the eyepieces. To achieve sharpest focus:
1. Rotate the objective turret (5) to the 2x position . (Always begin by viewing a specimen at low
power, then switch to high power when needed).
2. Turn the focus adjustment knob (11) until the specimen comes into focus. If there is not
enough travel in the focuser mechanism to reach focus, it may be necessary to loosen the
pillar stand locking bolt (12) and slightly raise or lower the entire binocular head assembly
until the image becomes sharp.
3. Next, while looking through the eyepieces, adjust the interpupillary distance by sliding both
eyepieces side to side until the whole field of view can be observed through both eyes at the
same time.
4. Finally, close your right eye and turn the left eyepiece diopter ring until the image is in sharp
focus through the eyepiece.
If higher power is desired, rotate the objective turret (5) to the 4x position and readjust the focus
knobs (11) until the specimen comes into focus.

Assembling Your Microscope
Before you can view through your Celestron microscope, the objective lenses must first be
attached.
Installing the Objective Lenses:
1. Remove the three objective lenses from their individual containers. Unscrew the container
lids from the threaded portion of the objective lens.
2. Thread the end of the 4x objective lens into one of the holes on the objective lens rotator (3).
It may be necessary to lower the specimen stage (6) by turning the coarse focus knob (12).
3. Now turn the objective rotator to the next opening and thread each of the remaining
objective lenses into the remaining holes.
Your microscope is now ready to view specimens.
Microscope Operation
Powering the illuminator:
Your Celestron microscope has a built-in illuminator powered by 110v AC power. To power the
illuminator:
5. Plug the power cord (11) into a wall outlet.
6. Turn the power switch (9) to the "on" position.
To regulate the amount of light shining on the specimen, rotate the diaphragm dial (7). The
diaphragm dial has five openings of different sizes which allow different amounts of light to pass
from the illuminator.
Viewing a Specimen
To view a specimen:
3. Press downward on the back portion of the spring-loaded specimen holder clips (13) to raise
the front of the clips off of the specimen stage (6).
4. Place a specimen slide under the specimen holder clips (13) and center the specimen directly
over the condenser lens .
You are now ready to focus and view the specimen, but first you must take some precautions so
as not to damage the specimen slide or objective lens. Your microscope is equipped with a focus
travel safety screw (14) which allows you to regulate the range of travel on the focuser. This
assures that the objective lenses will not accidentally come in contact with specimen slide,
breaking the slide or scratching the objective lens. To adjust the travel on the focuser
mechanism:
1. Lower the specimen stage by rotating the course focus adjustment knobs (12).
2. Partially unscrew the focus travel safely screw (14) so that about 1 inch is sticking up.
3. Turn the objective lens rotator (3) until the 40x lens is directly over the light condenser (5).
4. Use the focus knobs (12) to raise the stage (6) until the tip of the lens is slightly above the
specimen slide. (Be careful not to touch the slide to the objective lens).
5. Thread the focus travel safely screw (14) down until it stops against the focuser mechanism.
6. Rotate the knurled locking nut downward to lock the safety screw in place.

7
Focusing:
Now that the specimen slide is placed directly under the objective lens, use the course focus
knob (12) to focus on the specimen.
•Always start with the lowest power (4x objective lens) and switch to higher power by rotating
the objective lens rotator (3). Be cautious not to let the objective lens touch the specimen
slide when changing to higher power.
•Use the fine focus knob (10) to change the depth of field on the specimen you are observing.
•If you run out of upward travel before reaching sharp focus, you can unscrew the focus travel
safety screw (14) to allow for more upward travel. Once again be careful not to let the
objective lens touch the specimen slide.
Replacing the illuminator lamp:
1. Raise the specimen stage (6) to its highest position by rotating the course focus adjustment
knob (12).
2. Unscrew the black metal illuminator housing (8) and lift it straight up over the lightbulb.
3. Turn the lightbulb counterclockwise while gently pushing down.
4. Replace with a new 20W tungsten bulb.
5. Slide the illuminator housing back over the lightbulb and thread into place.

Assembling Your Microscope
Before you can view through your Celestron microscope, the eyepiece housing, eyepieces and
objective lenses must first be attached. To attach the eyepiece housing:
1. Remove the microscope body from its packaging by lifting it by the stand column (5).
2. Unthread the locking screw (4) located on the side of the microscope body just above the
objective lens changer (21).
3. Place the round angled end of the eyepiece housing (3) inside the circular opening at the top
of the microscope body. The round eyepiece housing adapter is slightly angled and should
slide under the two metal tabs on the inside of the microscope body opening.
4. Secure the eyepiece housing by tightening the locking screw (4).
Installing the Binocular Eyepieces
1. Remove the two 10x eyepieces from their individual containers.
2. Slide the narrow end of the eyepiece barrel into each of the eyepiece holders on top of the
eyepiece housing.
Installing the Objective Lenses:
4. Remove the four objective lenses from their individual containers. Unscrew the container lids
from the threaded portion of the objective lenses.
5. Thread the end of the 4x objective lens into one of the holes on the objective changer (21). It
may be necessary to lower the specimen stage (18) by turning the coarse focus knob (8).
6. Now rotate the objective changer to the next opening and thread each of the remaining
objective lenses in order of power (10x, 40x, 100x) into the remaining holes.
