2.17.3 Cleaning the Oil Darkfield Condenser
1. When using oil immersion, once you have finished using the oil darkfield lens,
you will need to clean the lens and specimen of the oil before it dries.
2. You can wipe the lens with a soft nonabrasive cloth to remove the oil. If you
want to use a cleaner, you can use cigarette lighter fluid to safely remove the
oil, as it will break it down. Do not use alcohol based solvents, as they
dissolve the cement used to in assembly of the lens (thus breaking your
objective).
3. The specimen itself can be discarded, or if desired, you could clean it up and
store it for later use. The specimen may also be left with the oil on it, as you
will still need to apply more for use later, however it may dry up and cloud
your specimen. Cleaning is recommended.
