BEAM DELIVERY OPTICS PAGE | 94
Shut down the laser and carefully inspect each optic in the beam delivery path, including the laser’s out-
put coupler. Remember that optics are fragile and must be handled carefully; preferably by the mounting
ring only. If the optic requires cleaning, refer to Maintenance for cleaning instructions. Use only
recommended cleaning materials (see first table in this chapter) to prevent scratching delicate optical
surfaces.
If the focusing optic is pitted, it must be replaced immediately. Because of the extremely high power
density of v40 lasers, pits or debris on the lens surface may absorb enough energy from the focused
beam to crack the lens. If this happens, other optics in the beam path may be contaminated or damaged
as well.
Danger: 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 CO2 laser radiation is emitted through the aperture. Corneal damage or
blindness may result from exposure to laser radiation.
Caution: Possible Equipment Damage
A risk of exposure to toxic elements may result when certain optical or beam delivery components
are damaged. In the event of damage to laser, marking head, or beam delivery optics, contact
NOVANTA, Inc. or the optics manufacturer for handling instructions.
