Remedy
OPTICAL ISSUES
Clean the slide or use a new specimen if sample is
destroyed
Clean the objective and eyepiece lenses
Clean the lens with lens cleaner or a nonabrasive
lint free cloth, as well as spray with compressed air
Adjust the height of the microscope with the focus-
ing knob on the focusing rack until image appears
in focus. Note: Higher magnification will require
the head to move closer, while lower will require
more distance between the sample and the lens.
Secure the slide to the stage with clips or another
manner so that the sample does not move
A light source must be used with this model micro-
scope to view a sample (ring light, built in illumina-
tor, or gooseneck illuminator)
The light source used is not bright enough, or is set
to too low of an intensity setting. Adjust setting to a
higher or change light sources
Thoroughly clean tall lenses with lens cleaner or a
lint free nonabrasive cloth
