“Those handheld green lasers pointers may not be as harmless as you thought.”
“NIST Tests Underscore Potential Hazards of Green Laser Pointers”
“Using a low-cost apparatus designed to quickly and accurately measure the properties of handheld laser devices, National Institute of Standards and Technology (NIST) researchers tested 122 laser pointers and found that nearly 90 percent of green pointers and about 44 percent of red pointers tested were out of compliance with federal safety regulations. The NIST test apparatus was designed so that it can be replicated easily by other institutions.”
