Troubleshooting

This section provides many useful tips on how to solve common 

problems while setting up or using the The Professor compound 

microscope:

I can’t see an image.  I only see a partial image. 

• Check to see if you need new AA batteries.

• Check to see if the LED lights are turned on by pushing the 

light button to the right or left on the base.  

NOTE:

Switch the button right and the illuminator (lower) light will

turn on to view a standard microscope slide.  Switch the button left

and the upper stage light will turn on to view macro (large) and

opaque specimens.

• Check to see if the objective lens is clicked into place.

• Turn the disc diaphragm, located underneath the stage, to 

adjust the amount of light for viewing the specimen.

It is difficult to get the image in focus.

• Adjust the coarse focus knobs slowly.

• Check to see if there has been damage to the objective 

lenses or eyepiece.  If the lenses/eyepiece are dirty, use lens 

paper and distilled water to rub gently to clean

NOTE: 

Never rub the lenses/eyepiece when it is dry.  This can cause

static charge that will attract dirt.
