5.7 Cleaning the Collimating Mirror
Perform the instructions in this
section ONLY if there is a
problem with the mirror.
Before opening any part of the
head, clean off the dust and/or
process debris using an
exterior cleaning towel
(PLTLS0023) or equivalent.
1. Remove the FiberCUT
®
HR head
to a clean area.
For steps 2 to 4, see
2. Loosen, but do not remove the (4)
captive M4 SHCS securing the
collimating mirror spacer cap to the
collimating mirror spacer block.
3.
CAREFULLY
, pull the collimating
mirror spacer cap straight out to
remove it.
Take care not to damage the sides of
the collimating mirror by contacting
the collimating mirror spacer block.

Now is also a good time to check the
water input/output fittings
(PLFTG0104).
If necessary, unthread the old fitting(s)
and thread in a new one.
Verify the new fitting(s) do not leak.
4. Inspect the collimating mirror and
either:
Clean it (proceed to step 5).
OR
Replace it (proceed to
).
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.
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.
5. Hold the optic by its edges and blow
any dust or lint particles off with low-
pressure dry nitrogen (2 to 5 psi) or air
from a blow bulb.
NEVER USE SHOP AIR BECAUSE IT
CAN CONTAIN OIL AND WATER.
If this does not remove all the
contamination, continue to step 6.
