| Laser danger warning sign. Exposure to laser radiation can be a health hazard. Very high power lasers may cause skin burns. Even at moderate powers,laser radiation can be hazardous,in particular to eyesight. Because of high coherence,low beam divergence and high brightness laser beams entering the eye can be focused to a very tight spot on the retina and cause damage via thermal effects. Laser danger warning signs can often be seen in laboratories,production or other facilities where human exposure to laser radiation is possible. Here a red laser beam is hitting the sign | |
