2. Electrical System
a) The bulb intermittently lights and
goes out.
Bulb is nearly burnt out.
Replace the bulb.
A cord or connector is not properly con-
nected.
Check all cords and connectors to
connect them securely.

Use the correct bulb type.

a) The specimen cannot be brought
into focus.
The specimen is positioned beyond the
focusing range.
Adjust the hardware (or software) lower
limit to an optimum height.
Re-place the specimen within the
focusing range.
4. Observation Tube
a) Field of view of one eye does not
match that of the other.
The interpupillary distance is incorrect.
Adjust the interpupillary distance.
Incorrect diopter adjustment.
Adjust the diopter.
Different eyepieces are used on left and

Change one eyepiece to match the
other so that both sides are the same
type.
Your view is not accustomed to micro-
scope observation.
When looking into eyepieces, do not
stare at image from the beginning but
see the overall field of view. It is some-
times recommended to turn your eyes
away from the eyepieces, look far off
and look into the eyepieces again.
