Stereoscopic microscopes are used for viewing 3-dimensional objects, inspection or assembly of small 
parts, and for dissection of biological specimen.  They provide an upright, unreversed image which 
permits easy manipulation of the object being viewed while looking through the microscope.  They are 
designed for viewing solid objects at low magnification, but they will also permit viewing of some 
transparent specimen slides. 
 
For optimum viewing satisfaction, follow these simple procedures.  Nomenclature used to describe 
components and controls can be identified by referring to the diagram at left. 
 

UNPACKING 
 

Do not touch any of the lens surfaces while handling the microscope.  Dust, dirt, fingerprints can damage 
the delicate lens surfaces or adversely affect image quality. 
 
Remove microscope stand and head assembly from carton.  Remove rubber eyeshields, dustcover and 
warranty card.  Remove tension adjustment rod (used to adjust focusing tension), “L hex wrench” (used to 
remove locking set screw on stage plates), and 2 contrast plates one white and one black (80mm 
diameter).  Your microscope is also supplied with a translucent white stage plate (80mm diameter), which 
is already mounted in the microscope base. 
 
Examine packing material before you discard it.  Retain the styrofoam container in case you need to 
transport, store, or return the microscope for service.  If it becomes necessary to ship the microscope for 
any reason, pack it in the styrofoam container, and then pack the styrofoam in another corrugated 
shipping container for optimum protection.  Use of the styrofoam alone will not provide adequate 
protection in transit, and will void your warranty. 
 
 

ASSEMBLY & OPERATION

 

 
1.  Install rubber eyepiece shields over top of eyepieces, with the flared portion of the shields positioned 

at the outside edge of eyepieces.  These help block out undesired light reflections, and to position 
your eyes at the proper point above the eyepieces. 

 
2.  Please observe that the head rotates 360 degrees.  To position the binocular head in stand, loosen 

knurled head locking screw.  Rotate head to face either forward or backward, whichever suits your 
preference or needs.  Then, tighten knurled head locking screw. 

 
3.  This model is furnished with three stage plates.  The translucent white plastic plate is used when 

viewing transparent specimen slides or for viewing some specimen thin enough through which light 
can pass (insect wings, etc.). The black or white contrast plate can be used when viewing opaque 
objects or for dissecting.  Choose plate providing best contrast with specimen.  

 

To switch plates, use the supplied “L hex wrench” to loosen set screw at front of base, only enough to 
permit removal of plate.  Replace plate and tighten set screw. 

 
4. 

Observe that the main voltage of your microscope is labeled on the back of the base.  Make 
certain that your voltage is 120v. Insert microscope plug into matching voltage outlet.

 

 
5.  There are three rocker type light controls located on front surface of microscope base. 
 

MAIN  =  Turns power on and off 
“I”   

=  Turns incidental light on (top illumination) 

“T”   

=  Turns transmitted light on (substage illumination) 

 

 

 

Transmitted and incidental illumination combined can provide extra illumination for certain objects 
where additional top illumination will enhance the object being viewed.
