Use of Immersion Objectives
1) Focus the specimen with a low power objective.
2) Put
a drop
of immersion
oil on
the specimen
slide and
the front
lens of the immersion
objective.
3) Turn the revolving nosepiece to bring the immersion objective into the light path, and focus
with the fine adjustment knobs.
NOTE:
© For
immersion
condensers
such as an achromatic-aplanatic
condenser or Abbe
condenser, remove the specimen from the mechanical stage and place a drop of
immersion oil on the front lens of the condenser.
Then, place the specimen on
the stage and slowly raise the condenser until firm contact with the underside of
the specimen slide is made.
© Care should be taken to prevent oil bubbles from forming in the oil film between
condenser and specimen slide.
If any, re-apply immersion oil, for these bubbles
greatly deteriorate the lens performance.
© After use carefully wipe off the immersion oil deposited on the lens surfaces
with gauze moistened with xylene.
Never leave oil on the lens surfaces after use
as oil remnants will seriously impair the performance of the lens system.

Photomicrography
The Olympus Photomicrographic
Equipment
Model PM-10AD
is uniquely qualified to be
used with the BHS
microscope for routine and advanced photomicrography.
A separate,
detailed instruction manual is available for the PM-10AD camera system.
For quick reference, however, you may want to refer to the following pointers when using
the PM-10AD.
