Using the 100X oil immersion objective

} The designated immersion oil should be applied to the top lens of

the 100X oil immersion objective. Otherwise, the observed image

will be unable to be focused on.

Always use the immersion oil supplied by Olympus. If you

CAUTION

use immersion oil other than supplied by Olympus, the

proper optical performance cannot be demonstrated.

Bring the specimen into focus using objectives in the order from lower

magnification to higher magnification.

Before engaging the oil immersion objective in the light path, apply a

drop of the immersion oil onto the specimen at the area to be observed.

Rotate the revolving nosepiece to engage the oil immersion objective

in the light path and bring the specimen into focus with the fine

adjustment knob.

· If the oil contains air bubbles, the image will be degraded.

CAUTION

Make sure that the oil is free of air bubbles.

· To remove bubbles, rotate the revolving nosepiece slightly

to move the oil immersion objective by one reciprocation

or two.

} The condenser of this microscope provides the full performance

when oil is placed between the slide glass and the front lens of the

condenser. If oil is not applied there, the observation image may

become slightly dark.

After use, lower the stage and rotate the revolving nosepiece for 90

degrees to remove the objective to which the oil is applied. Then,

thoroughly wipe off the immersion oil from the front lenses of the

objective and the condenser with cleaning paper or gauze slightly

moistened with absolute alcohol. Wipe off the immersion oil from the

specimen top in the same procedure.

If the objective is left for some time attached with the

CAUTION

immersion oil, the oil is hardened to impede the proper

observation.

· If immersion oil enters your eyes or contacts your skin,

CAUTION

immediately take the following treatment.

Eyes: Rinse with fresh water (for 15 minutes or more).

Skin : Rinse with water and soap.

· If the appearance of the eyes or skin is altered or the pain

persists, immediately see your doctor.
