CX21 MAINTENANCE MANUAL
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.
Eyepiece
Check it by rotating the eyepiece
after clamping screw is loosened.
(Wipe carefully and gently so as
not to damage the lens coating.)
Objective
Dirt is not directly seen, but
dirt and dust particles affect
the microscope image.
Condenser
Check the top lens and filter if
conspicuous dirt is not seen.
Collector lens part
Check it if conspicuous dirt
is not seen.
(Dust and dirt particles here
have minimal effect on the
image. However, the overall
appearance requires inside
lens cleaning.)
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.
