2-2 How to find dirty portion through observation
1) Close the aperture iris diaphragm.
(When the aperture iris diaphragm is closed, it facilitates finding the dirt particles
because the depth of focus increases and the dirt position bring into focus. However,
very small dirt particle may not be found in this method.)
2) Observe a specimen through the eyepiece.
If dirt is seen by observing it, look for the portion where stains or dust is adhered by
following the description below.
Note:
If dirty portion can not be identified in the above, it is assumed that internal lens and
prism are contaminated.
In this case, please contact your Authorized Olympus dealer
.
