A laser warning symbol. 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.
To give another example, of a more powerful laser—the type that might be used in an outdoor laser show: a 6-watt green (532 nm) laser with a 1.1 milliradian beam divergence is an eye hazard to about 1,600 feet (490 meters), can cause flash blindness to about 8,200 feet (1.5 mi/2.5 km), causes veiling glare to about 36,800 feet (7 mi; 11 km ...
Moderate and high-power lasers are potentially hazardous because they can burn the retina of the eye, or even the skin. To control the risk of injury, various specifications – for example ANSI Z136 in the US, EN 60825-1/A2 in Europe, and IEC 60825 internationally – define "classes" of lasers depending on their power and wavelength.
Now, the Newark branch of the FBI is warning residents against another dangerous trend: pointing lasers at them. Are those drone or aircraft lights? Graphics explain the difference.
Pilots of aircraft that have been misidentified as drones — amid an uptick of mysterious sightings in recent days — have been hit in the eyes with lasers, the FBI revealed Monday. “FBI ...
The Spyder III Pro Arctic looks more like a lightsaber than an ordinary laser pointer. The Laws and Lasers: Dangers of Cheap, Powerful Devices Outracing Regulation
Lasers are usually labeled with a safety class number, which identifies how dangerous the laser is: Class 1 is inherently safe, usually because the light is contained in an enclosure, for example in CD players; Class 2 is safe during normal use; the blink reflex of the eye will prevent damage. Usually up to 1 mW power, for example, laser pointers.
