Dangers of laser beams
WebThe eye is the most susceptible to damage from laser radiation. Upon exposure, the cornea and the lens of the eye (located at the front of the eye) magnify and focus the radiation on the retina (located at the back of the eye). Direct exposure to a laser beam or a reflection of a laser beam may burn the retina causing partial or complete blindness. WebDec 28, 1998 · A laser gives light in one small beam.

WebIdentify a laser’s class by reading the FDA warning label. Most red laser pointers are Class 2 and radiate less than 1mW of power. Class 2 lasers are safe if the beam accidentally enters the eye for a short period. The aversion response (blinking or turning the head) is fast enough (0.25 seconds) to prevent injury from the laser exposure. WebTo give some guidance on adequate handling and required precautions, laser devices are assigned to different safety classes, with class 1 being the least dangerous (containing e.g. lasers with microwatt power levels) and class 4 the most hazardous one.Note that the assignment to a laser safety class depends not only on the laser power, beam quality …
