There is no specific threshold between a powerful laser beam, a potentially hazardous one, and a clearly dangerous beam. The following are some guidelines. Bright Light Hazard Even a 5 milliwatt laser pointer can be a potential hazard if the green laser light distracts or temporarily flashblinds a person such as a pilot. This is why you…
Blue-light Hazard is defined as the potential for a photochemical induced retinal injury resulting from radiation exposure at wavelengths primarily between 400 nm and 500 nm. The mechanisms for photochemical induced retinal injury are caused by the absorption of light by photoreceptors in the eye. Under normal conditions when light hits a photoreceptor, the cell…
