o
Acetone is especially helpful with
eliminating haze on cover glasses.
o
If using acetone, proceed slowly
enough so that the liquid has time to
evaporate.
o
Lint free cotton swabs (PLOCK0005
– Texwipe 6 inch swabs, or
equivalent) may be helpful to
remove concentrated contaminants.
If the optic is completely clean, proceed
to step 18.
18. Reassemble the optic according to the
appropriate section of this document.
Recommended best practices include:
o
Blow any dust, lint, debris, etc. off
the seals and rings using low-
pressure dry nitrogen (2 to 5 PSI) or
air from a blow bulb.
o
Gently
shake the assembled optic
near your ear to verify no
components are loose.
o
Tighten any components as
necessary.
o
Before reinstalling, inspect the
assembled optic again to verify it is
clean and unscratched.
o
If the optic is not going to be
reinstalled immediately, cover it with
painter’s tape or equivalent to keep
out contaminants.
Take care no adhesive gets on the
optic surface.
