Eye Safety, Laser
Laser eye safety is a measure of how vulnerable the eye is to damage from a particular Laser source. This vulnerability is primarily affected by the output power
and the Wavelength (color) of the laser light. Communication lasers are typi
cally available in only a few wavelengths: 780nm, 850nm, 980nm, 1310nm and
1550nm. The eye is much more sensitive to short wavelengths such as 780nm
than 1550nm. Wavelengths above 850nm are invisible to the eye, but still ca
pable to causing damage. Class I laser devices are the safest. Class III laser
devices are the least safe. Eye safety requirements in the US are specified by
CDRH (21 CFR 1040.10 & 1040.11).
