12.3.3 Dust Cleaning
Dust on optics can be very tightly bound by static electricity.
Blowing removes some dirt; the remainder can be collected by the
surface tension of a wet alcohol swab. Acetone helps promote
rapid drying of the optic to eliminate streaks.
Action
1. Blow off dust.
2. If any dust remains, twist lens tissue around a swab, soak in
alcohol, and wipe the optic in one direction with a gentle
figure-eight motion.
3. Repeat as necessary.
4. Repeat the steps above, using acetone.
12.3.4 Cleaning Heavy Contamination
Fingerprints, oil, or water spots should be cleaned immediately.
Skin acids attack coatings and glass, and can leave permanent
stains. Cleaning with solvents alone tends to redistribute grime.
These contaminants must be lifted from an optical surface with
soap or other wetting agent. The optic is then rinsed in water and
the water removed with alcohol. Acetone helps speed drying and
helps eliminate streaks from forming.
Action
1. Blow off dust.
2. Using a soap-saturated lens tissue placed around a swab, wipe
the optic gently in a figure-eight motion.
3. Repeat as necessary.
4. Repeat this procedure with distilled water.
5. Repeat again with alcohol.
6. Repeat once more with acetone.
12.4 Cleaning the Chin Cup and Forehead Rest
WARNING!
Strong solvents such as Acetone or Methyl Alcohol
will damage the chin cup and forehead rest.
u
Use a gentler disinfectant such as isopropyl alcohol.
Action
1. Clean the chin cup and forehead rest with a disinfectant such
as isopropyl alcohol.
2. If the ocular lens is splashed while cleaning the patient head
mount assembly, gently wipe the front window lens (see
Cleaning the Front Window Lens) with a soft lens tissue to
avoid spotting.
