3) Raise the condenser till the top lens is close to the opening of stage. Place a drop of
immersion oil on the top of the lens of the condenser.
4) Place the slide on the stage. Raise the condenser and let the oil
drop contact the bottom of the slide. If air bubbles exist in the oil,
clean the oil from the condenser lens and bottom of slide with a
camera cleaning paper and repeat the procedures.
5) Follow the procedures in this manual to bring the sample on slide
in focus and observe.
6) When using the 100X oil darkfield objective, you will need to drop
the immersion oil and adjust the iris ring ( Fig. 14 ) to get proper
brightness and contrast of view field.
Note
：

The condenser won
’t work well if no oil drop applied on the condenser
