■Safety
VISIBLE AND INVISIBLE
SEMICONDUCTOR LASER
The light emitted from laser diodes, can cause retinal damage if viewed directly.
Never look directly into the laser beam or through any lenses or fibers when the
system is operating.
For optical axis alignment or other operations, we recommend the use of an
infrared-sensitive camera (ITV) or wearing protective goggles.
