Chapter 5 Miscellaneous Operations
● Handling of the Immersion Oil
Use a minimum quantity of oil. If too much oil is applied, surplus oil may flow out onto the
stage and the condenser and degrade performance.
After completing oil-immersion observation, be sure to clean the objective, condenser, and
any other parts that may be stained by oil. Any oil residue left on the lenses of oil-immersion
type objectives or adhesion of oils on the front lens of dry type objectives will degrade image
quality.
Use petroleum benzine to wipe off oil and finish with absolute alcohol (ethyl or methyl
alcohol). If petroleum benzine is not available, use methyl alcohol instead. In that case, wipe
off the oil several times (generally 3 to 4 times) as the detergency of methyl alcohol is
weaker than petroleum benzine.
WARNING
When handling petroleum benzine and absolute alcohol, be sure to follow
the instructions provided by the manufacturers. Since they are highly
flammable take great care when handling them.
● Cautions on Handling the Immersion Oil
• Close the container cap tightly after use. Make sure that the cap is closed tight after
refilling the container. Check the cap periodically to make sure it has not come loose,
allowing oil to leak out.
• Do not press the container hard. Oil may splash out.
• If you find an oil drips around the container, wipe them off.
• Avoid contact of immersion oil with eyes or skin. In the event of contact with eyes or skin,
take one of the following measures although Nikon immersion oil does not contain any
toxic ingredients.
◊ Contact with skin:
◊ Contact with eye:
• Do not leave immersion oil in the sun (ultraviolet rays may damage it).
1 Oil-Immersion Observation
Rinse your skin thoroughly with soap and water.
Rinse your eye thoroughly with water (more than 15
minutes) and see a doctor.
