8 Appendix A
– Cleaning Non-Metal Optics
Optics are very sensitive to dust and
debris. It is extremely important to
take every possible precaution to
ensure the optics remain pristine.
Clean optics in a dust free air-conditioned
room.
Before opening any part of the head, clean
off the dust and/or process debris using an
exterior cleaning towel (PLTLS0023) or
equivalent.
ALWAYS handle optics by their edges,
never touch the optical surfaces.
ALWAYS wear powder free gloves or finger
cots when handling optics and optic holders.
Inspect the optics with high power
illumination, such as Laser Mechanisms pen
light (PLTLS0021) under 2X magnification.
If installing a new optic, inspection and cleaning
are still recommended.
Laser Mechanisms Inc. cannot be held
responsible for any damage to optics resulting
from improper cleaning or handling.
1. Wash hands with soap to remove all oils,
and then put on powder free gloves or finger
cots.
2. If necessary, remove the optic(s) according
to the appropriate section of this document.
3. Hold the optic by the edge and inspect it.
If you see any scratches or pits, replace
the optic.
4. Hold the optic by its edges and blow any
dust off each side with low-pressure dry
nitrogen (2 to 5 PSI) or air from a blow bulb.
DO NOT USE AN AIR COMPRESSOR.
5. Secure the optic by its edge with the curved
side facing up.
A fixture may be helpful. Consult your
Laser Mechanisms Sales Engineer for
assistance.
6. Fold a clean lens tissue (PLOCK0014
–
Texwipe Absorband Wipes
– or equivalent)
so there are several layers and soak it with a
non-sterile solution of 70% isopropyl
alcohol/30% USP purified water pre-filtered
through a 0.2 micron filter (Texwipe TX167
or equivalent).
7. With the soaked lens tissue gently scrub the
optic with a circular motion, then slowly wipe
in one direction.
8. Turn the optic over (flat side facing up).
9. Using a new lens tissue, repeat steps 6 and
7.
10. Inspect the optic.
If you see any scratches, replace the
optic and return to step 3.
If you see any debris, streaks, or
cloudiness, proceed to step 11.
If the optic is completely clean, proceed
to step 18.
11. Secure the optic by its edge with the curved
side facing up.
12. Fold a clean lens tissue so there are several
layers and soak it with isopropanol.
Isopropanol is also known as
2-Propanol or UN1219.
