12.3 Cleaning optical components
12.3.1 Brush Cleaning Method
This technique is ideal for cleaning smaller optics, including lenses,
and involves holding a folded lens tissue with a hemostat to brush
the surface clean.
NOTE
Edges on mounted optics
are often hard to reach.
u
Wrap a lens tissue around a swab.
u
Soak the covered swab in acetone.
u
Brush around the edge of the lens and then across the middle
using a continuous figure-eight stroke.
u
Repeat if necessary.
Action 1. Fold a lens tissue so as not to touch the part of the tissue that
will make contact with the optic. The fold should be about as
wide as the optic.
2. Hold the tissue with hemostats parallel to and near the fold.
3. While holding the optic, using tweezers if necessary, blow off
any dust.
4. Soak the tissue with acetone.
5. Brush the fold in the tissue across the surface of the optic using
light pressure.
6. Repeat as necessary until the optic is clean, making sure new
lens tissue is exposed with each wipe.
12.3.2 Wipe Cleaning Method
For heavier cleaning of lenses and mirrors, this method involves
wiping an optic with a lens tissue by hand.
Action 1. Blow off dust.
2. Fold a lens tissue as with the brush method.
3. Apply acetone to the tissue.
4. Holding the lens tissue in your hand with the fold near the tip
of your fingers, apply uniform pressure while gently wiping
across the surface of the optic.
5. Repeat as necessary until the optic is clean, making sure new
lens tissue is exposed with each wipe.
