Use of the S100x oil-immersion objective
The MT-10 series microscopes are equipped with a S100x N.A. 1.25 oil immersion
objective. Please follow these instructions for using this objective:
•
Focus the image with the S40x objective.
•
Turn the revolving nosepiece so the S100x objective almost reaches the
click-stop.
•
Put a small drop of immersion oil on the centre of the slide.
•
Now turn the S100x objective so that you feel the click stop.
•
The front lens is in contact with the immersion oil.
•
Look through the eyepiece (B) and focus the image with the fine
adjustment knobs (I).
•
The distance between the lens of the objective and the slide is only 0.14
mm!
•
In case there are small bubbles visible turn the S100x objective a couple of
times left/right so that the front of the objective moves in the oil and the bubbles
will disappear.
•
After using the S100x objective turn the fine adjustment knobs (I) up until
the front lens doesn’t touch the oil any longer.
•
Always clean the front lens of the S100x objective with a piece of lens paper
that is moistened with a drop of xylol or alcohol.
•
Clean the slide after use as well.
Caution
•
Never put a drop of xylol or alcohol directly on the lens of the objective. It
could enter the objective and dissolve the glue that holds the lenses!
•
Avoid oil contact with any of the other objectives!
