Thank you for purchasing The Professor Stereo Microscope by
Ken-A-Vision.
Welcome to the world of stereo microscopy. Here are a few things to get
you started. First, be sure the following items are included with your unit:
The Professor Stereo Microscope
(3) AA batteries
THE PARTS OF A STEREO MICROSCOPE
1. Eyepieces: Two 10x lenses that you use to look through.
2. Objective Lenses: The Professor Stereo Microscope consists of
two objective lenses; 2x. When combined with the 10x eyepiece
lens you get total magnifications of 20x (2x times 10x)
3. Stage Plate: The flat platform where you place your specimens.
The metal clips can hold some of your specimens in place. This
stage plate also has 2 sides; white and black.
4. Illuminator: The light source that is above the stage and is battery
operated with 3 AA batteries.
5. Focus Knob: Use this knob located on each side of The Professor
Stereo Microscope to focus the image of your specimen.
6. Base: The bottom of the stereo microscope that is used for
support. The push button located on the back of the stage plate
turns your microscope on/off. Batteries are located in the bottom
of the base.

Installing / Replacing Batteries

Professor Stereo Microscope.
5. Insert the base plate into the notches and push close.
How To Use Your Stereo Microscope
1. Remove The Professor Stereo Microscope from its storage
location by grabbing the arm of The Professor Stereo Microscope
with one hand and place the other hand below the base.
2. Put a slide or specimen on the stage plate.
3. To view through the eyepiece lenses, look through the eyepiece.
Now focus your stereo microscope.
4. Don't forget to turn on The Professor Stereo Microscope.
Focusing
The proper way to focus The Professor Stereo Microscope is to turn the
focus knob to raise the head up until it stops. Then look through the
eyepiece and focus downward until the image is clear.
Taking Care of your Stereo Microscope
1. The Professor Stereo Microscope is a precision instrument, treat
it with care. When working with The Professor Stereo
Microscope be sure it is directly in front of you and any notes you
take are set beside your Professor Stereo microscope. This
method of viewing will limit the chance of accidentally knocking
The Professor Stereo Microscope off the table.
2. When the objective lens or eyepieces are dirty, the image will not
be very clear and sharp. To clean, use lens paper and distilled
water and rub the lens and/or eyepiece softly. Never rub the lens
when it is dry. (This can cause static charge that will attract dirt.)
