About laser pointers
Laser pointers are categorised as class 3R, 3B or 4. Class 3R has a maximum strength of 5mW. Class 3B has a maximum strength of 500mW, and laser class 4 are the laser pointers that have a strength in excess of 500mW.
Class 3B and 4 lasers shall have a visible and audible signal when they are on, and a device that stops the beam physically. An on/off button is not enough, you must actually be able to lock the laser pointer. The use of class 3B and 4 laser pointers requires eye protection, and are generally reserved for medicine, industry and research.
