Welcome:
Welcome to the amazing world of the microscope! A microscope opens
up hidden worlds everywhere. It is an essential tool in biology, chemistry,
geology, gemology, forensic sciences and more.
A microscope can show a world of life in a drop of pond water, it can
show living cells and their component parts. Crystalline structures show
the building blocks of materials. Rock samples can show ancient
microfossils. Harmless insects can look like ferocious monsters.
You now own a precision made microscope that can show you all of
these and much more.
Please take the time to read this manual and become familiar with the
proper operation of your microscope.
Getting Started:
First, insert 2 “AA” alkaline batteries in the base of the microscope. In
order to remove the bottom cover of the microscope you will need a
Phillips head (+) screwdriver. Insert the batteries as shown, making sure
that the (+) and (-) terminals are properly identified. Replace the bottom
cover and re-insert the screw. Do not over-tighten.
How to Use the OR 200XL:
In order to appreciate how easy this microscope is to use let’s run
through a simple observing procedure.
1)
Set the microscope on a sturdy flat surface like a desktop.
2)
Check that the eyepiece marked “5X” is in position, inserted into
the top of the microscope tube. If the “12.5X” eyepiece is in
position you can replace it by gently lifting it straight up and
replacing it with the “5X” eyepiece.
3)
Position the microscope so that it is pointed towards a window
(make sure that any blinds or curtains are open), or a desk lamp.
4)
Look down into the eyepiece. You can now tilt the microscope
back until you find a comfortable viewing angle by firmly gripping
the microscope tube and pulling it backward and slightly down.

5)
When looking into the microscope you will see the circular
viewing field. Reach around to the front of the microscope and
locate the mirror.
6) Tilt the mirror until the circular viewing field is at its brightest. The
mirror can tilt up and down and sideways to obtain the most
efficient illumination position.
6A) If the room lighting is poor you will want to use the built-in
electric illuminator. It is located in the mirror assembly under the
slide stage. Simply turn the mirror over. The light will come on
and you can adjust it for maximum brightness by moving it
slightly until the maximum light output shines through the hole in
the slide stage under the lens.
6B When you have finished using the electric illuminator simply flip
the mirror assembly so that the mirror is face up and the electric
light will go out.
7)
Now locate a glass slide of a subject that interests you. Position
the slide under the two metal slide clips. (See diagram.) Move
the slide around until the sample is positioned over the small
opening in the stage.
8)
Now look down into the eyepiece and slowly turn one of the
focusing knobs. The microscope tube will move up or down,
depending on which direction the knob is being turned. You will
see the image of the sample get sharper and sharper as it
comes into the proper focusing position.
9)
You can now gently move the slide around to see different
sections of the sample. Note how clear and bright the image is.
10)
If you want to see more detail, lift out the “5X” eyepiece and
replace it with the “12.5X” eyepiece. You may have to slightly
adjust the focus. You have just increased the magnification from
80X to 200X.
11)
When you have seen enough, remove the glass slide and
replace it with another. (Note: It is usual practice to start
observing at low powers, so you may want to re-insert the
eyepiece marked “5X.”
