USING THE 100X IMMERSION OBJECTIVE
Fig. 25
Lx 500
The designated immersion oil should be in contact with the cover
lens of the 100X immersion objective. If not, the specimen will
appear distorted and dull. It is recommended that LABOMED
immersion oil is always used.
Immersion Process
:
1. Bring the specimen in focus using first the 10x, then 40x
objective.
2. Disengage the 40x cycling towards 100x, and place a drop of
immersion oil on the center point of the specimen.
3. Rotate the revolving nose piece to engage the immersion
objective and rotate the fine adjustment knob to bring the
specimen into focus
Caution:
(Since air bubbles in the oil will affect the image quality, make
sure that the oil is free of bubbles. To remove bubbles, rotate the
revolving nosepiece slightly to agitate the oil).
4. The condenser of this microscope manifests the full perfor-
mance when oil is placed between the slide glass and the front
lens of condenser. If oil is not placed there, the observed image
may appear dark.
5. After use, remove oil from the objective front lens by wiping with
lens tissue slightly moistened with an ether(70%) alcohol (30%)
mixture.
Caution:
If immersion oil makes contact with your eyes, rinse eyes out
throughly with fresh water. If immersion oil makes contact with
skin, wash affected areas with soap and water.
If prolonged discomfort is experienced, consult your physician
immediately.
