Maintenance
Debris or contaminants on the laser’s output coupler or external beam delivery components may affect
laser processing and lead to damage or failure of the optics and/or the laser. Carefully follow the steps
below to inspect and clean the optical components in the beam path. Before beginning the cleaning
process, read this entire section thoroughly to ensure that all cleaning materials are available and that
each step is completely understood.
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
1 Wear latex gloves or finger cots (powder-free) to prevent contamination of optical surfaces by
dirt and skin oils.
2 Never handle optics with tools; always use gloved hands or fingers.
3 Hold optics by the outer edge; never touch the coated surface.
4 Always place optics on lens tissue for protection; never place optics on hard or rough surfaces.
Warning: Serious Personal Injury
Ensure that DC power to the laser is turned off and locked out before inspecting optical components
in the beam path. Invisible CO

laser radiation is emitted through the aperture. Corneal damage or
blindness may result from exposure to laser radiation.
Caution: Possible Equipment Damage
Because of their smaller beam diameter, Firestar lasers have significantly higher power densities than
previous NOVANTA lasers. This means that any contamination on the laser’s output window (or on
any optic in the beam path) can absorb enough energy to damage the optic. Inspect the output
window and other beam delivery optics periodically for signs of contaminants and 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
