Microscope Operation
Powering the illuminator:
Your Celestron microscope has a built-in illuminator powered by 110v AC power. To power the
illuminator:
7. Plug the power cord into a wall outlet.
8. Turn the power switch (13) to the "on" position.
Your microscope is now ready to view specimens.
Viewing a Specimen:
Your instrument is provided with a specimen holder and a specimen mover. To view a specimen:
1. Use the clamp lever (19) to open the clamping arm of the specimen holder (6).
2. Place a specimen slide inside the holder and gently close the clamping arm against the slide.
3. Use the specimen mover handwheels (10 & 12) to position the specimen over the opening in
the specimen stage (18).
TIP:To position the specimen directly under the objective lens, first rotate the illuminator
brightness control wheel (11) to increase the brightness to its maximum setting. Then close
the opening on the iris diaphragm (16) until it is almost completely closed. You should see a
small beam of light projected onto the specimen slide. Now simply use the specimen mover
handwheels (10 &12) to move the specimen directly inside the beam of light.
4. Use the knurled ring to rotate the objective lens changer (21) until the 4x objective lens is
directly over the specimen (Always start with the lowest power objective and work you way
up to higher powers).
5. Look through the eyepieces while turning the coarse focus handwheel (8) until the specimen
comes into view. You may need to adjust the specimen mover handwheels (10 & 12) slightly
to center the specimen in the field of view. Warning: When focusing, be careful not to
raise the specimen stage so high that the specimen slide touches the objective lens.
Not only can you break your slide but you may also scratch the objective lens.
6. Finally, adjust the fine focus handwheel (9) until you reach the sharpest focus for your eye.
Never rotate both of the fine focus handwheels at the same time in opposite directions.
Otherwise the focusing mechanism will be damaged.
Tip: When viewing a specimen with the 100x objective lens, you can improve the resolving power
by placing a small drop of the cedar wood oil between the specimen and objective lens. For
specimen slides that you prepare yourself, always cover the specimen with a thin piece of
glass and place the oil on the cover glass. Do not put oil directly on the specimen sample.
Adjusting the Lighting:
Specimens of different size and thickness will require different levels of illumination. There
are three ways to change the amount of illumination when viewing a specimen; adjusting the
brightness control, adjusting the condenser and adjusting the iris diaphragm.
When viewing a specimen that is not transparent or dark in color you may need to
increase the amount of light to resolve certain features or details. This is best done by
simply increasing the brightness of the illuminator by rotating the Brightness Control
Wheel (11) all the way to its highest setting.
When viewing with the lower power (4x and 10x) objective lenses you will need to lower
the condenser lens (17) in order to spread the light over the larger field of view. To
change the position of the condenser, simply rotate the Condenser Adjustment
Handwheel (15) clockwise until the beam of light spreads wide enough to illuminate the
