A Eyepiece
With fixed lens that has a 20x magnification. Remove
the dust cover from the eyepiece and put it aside in a
safe place.
B Body Tube
Connected to the eyepiece and helps focus the
lenses.
C Focus Knob
Slowly turn the knob back and forth to focus an object
in the eyepiece. Notice what happens to the power
indicator as you turn the knob.
D Power Indicator/
Objective Turret
The turret has 3 lenses or objectives; 15x, 30x and
60x. The shorter the objective the lower the power
or magnification. The longest objective is the highest
power. To calculate the magnification you are using
multiply the value of the objective by the power of the
eyepiece (note the power indicator on the turret makes
this calculation for you) For example, turn the power
indicator to the longest objecting 60x and multiply the
power of your fixed eyepiece 20x - you will magnify
the object by 1200 times (note the at power indicator
reads 1200) This means that the object appears 1200
times larger than it appears to the naked dye.
E Stage Clips
2 clips hold the glass slide firmly onto the stage.
F Stage
Flat Platform with a hole in the center to allow
reflected light off the mirror or light source to enter the
microscope.
G Color Filter And
Aperture Wheel
The color filters are incorporated with in the stage.
Use these filters to add colors and enhance an image
in the eyepiece.
H Mirror/Light
Source
While holding the base down, pull on the arm to tip the
microscope back. Examine the mirror and light source
located below the stage to see how you can adjust
them and choose one or the other. The light source
turns on automatically when tipped upwards toward
the stage. The mirror gathers and reflects light into the
microscope.
I Base/Battery
Compartment
Place the microscope on its side. To remove the
protective plastic over, remove the screws with a
Phillips head screwdriver. Gently lift and the base will
open. Insert two “AA” batteries (not included) in the
base. Match the positive (+) and negative (-) poles
of the batteries with the markings on the base. To
replace lid, position it over the opening and replace
the screws.
