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.
If acetone is used as a cleaning solvent, a second follow-up cleaning of the optical surface using
alcohol is required. Otherwise, solvent residuals could damage your laser!
Important Note: To prevent streaking during the final alcohol cleaning, drag the lens wipe slowly
across the surface so that the cleaning liquid evaporates right behind the wipe.

Introduction
This 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.
To troubleshoot v40 lasers, it is necessary to understand the sequence of events that must happen
before the laser can operate. Before attempting any service, we advise you to read the entire
troubleshooting guide and review both the operational flowchart and the functional block diagram.
Symptoms and possible causes are highlighted by dark print and bullet points throughout this section.
Information about each symptom and cause can be found in the paragraphs following each heading.
