Eye safe wavelength
Webemitting (coherent) laser radiation in the wavelength range 180 nm to 1 mm. In previous editions, LEDs were included in the scope of this standard, and were also included in … Laser radiation safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations. Moderate and high-power lasers are potentially hazardous because they can burn the retina, or …
