Lightwave Safety Guidelines
General Laser Information
Lightwave/lightguide systems, their associated test sets, and similar operating
systems use semiconductor laser transmitters that emit light at wavelengths
between approximately 800 nanometers and 1600 nanometers. The emitted light
is above the red end of the visible spectrum, which is normally not visible to the
human eye. Although radiant energy at near-infrared wavelengths is officially
designated invisible, some people can see the shorter wavelength energy even at
power levels several orders of magnitude below any that have been shown to
cause injury to the eye.
