4. Engage the Magnus 100X Objective in the light path
by rotating the revolving nosepiece and focusing the
specimen with the fine focus adjustment knob.
The image view is poor if bubbles are mixed into
the oil, so be careful not to mix bubble in the oil.
a) The presence of bubbles can be checked by removing
the eyepiece lenses, fully opening the field iris
diaphragm and condenser iris diaphragm and looking
into the observation tube sleeve(s).
B) To remove the bubble, reciprocate the 100X objective
a few times by rotating the revolving nosepiece.
When the immersed objective is used, the condenser
can exhibit full performance if oil is applied to both the
bottom side of the specimen and the top surface of the
condenser. Without oil, the observed image becomes
slightly dark.
5. After use, remove the immersion oil on the objective
lens tip by wiping with gauze slightly moistened with
alcohol.
Do not use too much alcohol or solvent for these
chemicals may dissolve the lens adhesive agent.
