OPTICAL ISSUES
One side of the eld
of view is darker
The nosepiece is misaligned Turn the nosepiece unl it clicks into place
Stains or dust has accumulated on the objecve,
eyepieces, or base lens
Clean all lenses with lens cleaner or a lint free non-
abrasive cloth
The substage Abbe condenser is not seated level
(-2L only)
Loosen the locking screw holding the condenser in
place, then push up unl it is seated parallel to the
stage (level). The iris will sit at a slant if not, which
will cause uneven illuminaon

specimen
Clean the slide or use a new specimen if sample is
destroyed
Stains, dust, or dirt have accumulated on the lens Clean the lens
Unclear Image There is no cover slip on the slide (-2L only) Add a cover slip. The objecves are designed for
use with a 0.17mm cover slip, so it is a requirement
to use one for properly focused images. Using two
slides will cause a non-focusable situaon, as the
top slide is too thick for the objecve.
The cover slip is not standard sized (-2L only) Replace the cover slip with the appropriate 0.17mm
thickness slip
The aperture is not open to an appropriate
diameter
Adjust the aperture to have the light just larger
than the size of the condenser (on the upper light
housing or the condenser if using the -2L model)
Stain or dust has accumulated on the lens in the
inlet of the head
Clean the lens with lens cleaner or a nonabraisive
lint free cloth, as well as spray with compressed air
