1. Troubleshooting Guide

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) Rotate the revolving nosepiece to bring the immersion objective into the light path, and

focus with the fine adjustment knobs.

NOTE:

ill

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 bubbles appear, 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 perforrrance of the lens system.

Photomicrography

The Olympus Photomicrographic Equipment Model PM-lOAO is uniquely qualified to be

used with the BHTU microscope for routine and advanced photomicrography. A separate,

detailed instruction manual is available for the PM-lOAD camera system.

For quick reference, however, you may want to refer to the following pointers when using

the PM-lOAD.

Photographic Eyepiece

Use NFK photo eyepieces for photomicro-

graphy.

Insert the eyepiece

into the eyepiece tube

of the photo tube. (Fig. 20)

2. Mounting the Photographic Unit

Slip the body of the photographic unit over the

photo tube. Align the dots on photo tube and

the PM- lOAD body and clamp the camera unit

to the photo tube. (Fig. 211

3. Setting the Light Path Selector
