.
Important Note: Exercise great care when handling infrared optics; they are much more fragile
than common glass materials. Optical surfaces and coatings are easily damaged by rough
handling and improper cleaning methods.
Cleaning guidelines
•
Wear latex gloves or finger cots (powder-free) to prevent contamination of optical surfaces by dirt
and skin oils.
• Never handle optics with tools; always use gloved hands or fingers.
• Hold optics by the outer edge; never touch the coated surface.
• Always place optics on lens tissue for protection; never place optics on hard or rough surfaces.
• It may be necessary to use a cotton ball or fluffed cotton swab instead of a lens wipe to uniformly
clean the entire surface of small-diameter mounted optics.
• Before using any cleaning agents, read Material Safety Data Sheets (MSDS) and observe all
necessary safety precautions.
Caution: Possible Equipment Damage
Because of their smaller beam diameter, F201 laser lasers have significantly higher power densities
than previous NOVANTA lasers. This means that any contamination on the laser’s output coupler (or
on any beam delivery optic) can absorb enough energy to damage one or more optics in the beam
path. Periodically inspect the laser’s output coupler and all other beam delivery optics for signs of
contaminants and then carefully clean as required. In dirty environments, purge laser optics using
filtered air or nitrogen to prevent vapor and debris from accumulating on optical surfaces.
Important – F201 laser f201 and lasers do not have output windows located inside the faceplate.
NEVER disassemble the laser housing to inspect f201 optics. Instead, always connect nitrogen or
filtered air to the laser’s Gas Purge port to prevent vapor and debris from contaminating internal
optical surfaces.
