BX2 MAINTENANCE MANUAL
2-2 How to find dirty portion through observation
1) Stop down the aperture iris diaphragm.
(When the aperture iris diaphragm is stopped down, 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 moving the following components as well as a specimen.
For TV camera, check it by method shown below.
Photo eyepiece
Check it by rotating
the photo eyepiece.
(The dust particles will be
focused on the film plane.)
Eyepiece
Check it by rotating the eyepiece.
(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 it by loosening the
fixing screw and moving
the condenser forward or
backward.
Filter/Collector lens
Check it by rotating the filter.
(Dust and dirt particles here
have minimal effect on the
image. However, the overall
appearance requires frequent
cleaning. Wipe evenly since
this is a wide surface area.)
Note: If dirt particles do not move by moving the above components, it is assumed that
the lens and filter inside the microscope is contaminated.
In this case, please contact your Authorized Olympus dealer.
