Important Note:
If acetone is used as a cleaning solvent, a second follow-up cleaning of the
optical surface using alcohol is required.
Use a clean lens wipe on each pass. The wipe will pick up
and carry surface contaminants that may scratch optical surfaces or coatings.
5
Gently, and without applying pressure, drag the damp lens wipe across the optical surface in
a single pass. Do not rub or apply any pressure, especially when using a cotton swab. Drag
the wipe without applying any downward pressure.
6
Carefully examine the optic under a good light. Certain contaminants or damage such as
pitting cannot be removed. In these cases, the optic must be replaced to prevent catastrophic
failure.
7
Repeat Steps 4 through 6 as required, removing all traces of contaminants and deposits
Troubleshooting
The Troubleshooting section includes subsections:

The Troubleshooting section is designed to help isolate problems to the module level only. Problems on
circuit boards or the laser tube are outside the scope of this guide because they are not user-serviceable
assemblies; do not attempt to repair them. Contact Novanta or a Novanta Authorized Distributor for
repair information.
