INSTRUCTION MANUAL
Caution:
The maximum light intensity when using the 4x and 10x can damage the eyes!
When changing slides always start with the 4x objective again.
Safety device
To prevent damage to the objective lens, or breaking the slide, all types are equipped with a
pre-fixed safety device.
It is recommended to use slides of 1.0 – 1.2 mm thickness in combination with cover glasses
of 0.13 mm or 0.17 mm thickness
Use of the S100x oil-immersion objective
Some of the 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 (O) and focus the image with the fine
adjustment knobs (I).
•
The distance between the lens of the objective and the slide is only
0.14mm!
•
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 table (G) with the fine adjustment
knobs (I) downwards 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.
