2.5. Laser Beam Alignment

For optimal performance, you must align the input laser beam to the AGV3D enclosure. Use the alignment
fixture that is provided with the AGV3D to simplify the laser alignment procedure. The alignment fixture is
designed to work with the working laser beam, so a visible alignment beam is not necessary for UV and IR
wavelengths. The alignment targets will fluoresce under laser power, even for UV and IR wavelength lasers.
D A N G E R : The laser will be turned on during the alignment procedure. Follow all laser safety
precautions.
1. Do no stare into the laser beam, place your body parts in the beam path, or expose yourself
to reflections from powerful beams.
2. Wear eye protection. The danger to your eyes increases when optical instruments are used
in conjunction with the scan head.
W A R N I N G : The laser could burn the fluorescing target disks.
During laser alignment, it is critical that you only use sufficiently low power settings to
l
avoid burning the target disks.
In general, use as little power as necessary to see the laser spot on the fluorescing disks.

The values in

Small deviations in power are acceptable, if necessary.
