ILLUMINATION 

 

1.  If your model is not supplied with built-in illumination, it should be used where adequate natural or 

overhead light is available. 

 
2.  If your model is supplied with a port to accept an optional penlight illuminator, you can operate your 

microscope without this penlight illuminator, or you may elect to purchase optional #903 penlight 
illuminator (requires 2 each AAA batteries, not included). 

 

To install optional #903 penlight illuminator: 
 
a.  Remove chrome lamp holder and lamp assembly from body of penlight by rotating lamp holder in 

a counter-clockwise direction.  Remove white plastic tube from penlight (discard white tube) and 
insert 2 each AAA batteries into body of penlight (positive terminals facing up toward  lamp).  
Replace chrome lamp holder and lamp by screwing tip in a clockwise direction. 

 

b.  Insert penlight into black rubber-lined friction mounting port located immediately behind head of 

microscope. 

 
3.  Determine whether the black or white side of the stage plate will provide best contrast with the 

specimen to be viewed.  The white side will be used for most viewing.  It will always be required when 
viewing transparent specimen slides because it better reflects light through specimen slide. 
 
To reverse black/white plate, loosen locking set screw located at front of base with “L” hex wrench 
provided.  Insert plate with selected surface facing up.  Tighten locking set screw. 

 
4.  If your model has top (incidental) illumination only, select and position plastic stage plate as described 

under “3” above. 

 
5.  If your model has both top (incidental) and bottom (transmitted) illumination: 
 

Three switches are on top of base:  (1) main power on/off, (2) “I” switch controls incident (top) light, 
(3) “T” switch controls transmitted (bottom) light. 
 
This model is furnished with two stage plates.  The frosted glass plate is used when viewing 
transparent specimen slides or for viewing some specimen thin enough through which light can pass 
(insect wings, etc.).  On this model, locking set screw is located on one side of base. 
 
FROSTED GLASS PLATE MUST BE USED IF USING BOTTOM ILLUMINATION.  HEAT 
GENERATED IN BASE FROM BOTTOM LIGHT WILL WARP OR DAMAGE THE PLASTIC
