accumulated on the objective,
eyepieces, or Barlow lens. Clean the lens.
There is no cover slip on the
slide.
Add a cover slip. The objectives are
designed for use with a 0.17mm cover
slip, so it is a requirement to use one for
proper images.
The cover slip is not standard
sized.
Replace the cover slip with the
appropriate 0.17mm thickness slip.
The immersion oil has
accumulated on the dry
objective.
Thoroughly clean the objective lens with
lens cleaner or a lint free non-abrasive
cloth
No immersion oil is used with
the 100X objective.
Use immersion oil for better clarity and
resolution.
Used wrong oil. Use standard cedar wood oil.
The aperture is not open to an
appropriate diameter.
Adjust the aperture to have the light just

Stains, dust, or dirt has
accumulated on the inlet of the
head.
Clean the lens with lens cleaner or a non-
abrasive lint free cloth, as well as spray
with compressed air.

Adjust condenser height to the top of the
travel range, and then adjust down to
focus image.
Initial focus was at too high a
magnification.
Start focusing with the lowest objective
and then switch to the higher ones.
