Safety of Class 3R visible-beam lasers - Laser Safety Facts
网页WHAT IS A CLASS 3R LASER? Class 3R lasers are considered safe when handled carefully. There is only a small hazard potential for accidental exposure. For visible-light lasers, Class 3R lasers' output power is between 1 and 4.99 milliwatts. In the United States, both Class 2 and 3R lasers can be sold as "pointers" or for pointing purposes.
