Microscope Operation
Using the Illuminator Mirror:
Your Celestron microscope has a built-in Plano-concave illumination mirror which allows you to
illuminate the specimen from the bottom. The mirror has a flat side and a concave side. The
concave side will concentrate more light onto the specimen than the flat side. To illuminate a
specimen:
1. If it is daylight, tilt the illumination mirror (4) and reflect indirect sunlight through the bottom of
specimen stage (3).
WARNING: Never use the mirror to focus direct sunlight through your microscope.
Sunlight, if viewed directly can be very harmful and may permanently damage your eyes.
2. If viewing at night or indoors, away from sunlight, you can use a nearby desk or table lamp to
reflect light onto a specimen.
To control the amount of light reflecting onto the specimen:
1. Use the concave side of the illuminator mirror to focus more light on the slide. The concave
side will concentrate more light onto your specimen but will focus a smaller beam of light,
making it more sensitive to adjust.
2. If you are unable to adjust the mirrors enough to properly illuminate the specimen, you can
also tilt the stand column (7) backwards to change the position of the mirror.
Viewing a Specimen
To view a specimen:
1. Carefully place a specimen slide under the specimen holder clips (5) and center the
specimen directly over the hole in the stage (3).
Your are know 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 (6) which allows you to regulate the range of travel on the focuser. This
assures that the objective lens will not accidentally come in contact with the specimen slide,
breaking the slide or scratching the objective lens. To adjust the travel on the focuser
mechanism:
1. Raise the objective lens away from the specimen stage (3) by rotating the focuser knob (8)
backwards.
2. Unthread the focus travel safety screw (6) about 2/3 of the way.
3. Lower the objective lens over the slide until the tip of the lens is slightly above the specimen
slide. (Be careful not to touch the objective lens to the slide).
4. Thread the focus travel safely screw (6) upward until it stops against the focuser mechanism.
5. Rotate the knurled locking nut upward to lock the safety screw in place.
6. Now, turn the focus adjustment knob (8) until the specimen comes into sharp focus.
