INTRODUCTION
Thank you for your purchase of a Fisher Science Education microscope. Your new microscope
is a precision instrument carefully checked to assure that it reaches you in good condition. It is
designed for ease of operation and years of carefree use. The information in this manual probably far
exceeds what you will need to know in order to operate, troubleshoot and maintain your microscope.
However, it is provided to answer questions that might arise, and to help you avoid any maintenance
expense that may be unnecessary.
TYPES OF MICROSCOPES COVERED IN THIS MANUAL
The compound microscope combines two optical lens systems. The lens closest to the specimen
slide, the objective, magnifies the primary image and the top lens, called the eyepiece, further
magnifies the image. Magnification of the objective times the magnification of the eyepiece is the
total magnification produced by this combination of lenses. The image produced by the compound
microscope is upside down and reversed. Compounds are used for viewing standard 1” by 3” 1mm
thick transparent specimen slides with cover slips. Prepared specimen slides can be purchased to fit
the classroom subject matter or user can make his own specimen slides.
The stereo microscope is an instrument that incorporates two separate optical system aligned to
produce three-dimensional images. Primary uses of the stereo microscope are the inspection and
assembly of small parts, examining plants and insects, dissecting of biological specimen. Stereo
microscopes provide an upright, unreversed image that permits easy manipulation of the object being
viewed while looking through the microscope. Stereos are designed for viewing solid objects at low
magnification, but they will also permit viewing of some transparent specimen slides.
Digital microscopes have all of the features of a compound microscope or stereo microscope but
are enhanced with the addition of a built-in digital camera. With software included with these digital
microscopes, they become real time learning tools.
