Class 2 / Class II

A Class 2 laser is relatively weak. It normally would not harm an eye unless a person deliberately stared into the beam. Laser protective eyewear is normally not necessary. A Class 2 laser is not a skin or materials burn hazard. However, even a Class 2 laser can be a distraction, glare or flashblindness hazard for pilots and drivers. NEVER aim any laser towards an aircraft or vehicle that is in motion.

1. Classe 1: Output power can not cause eye damage.
2. Classe 2: The output power is less than 1 mW. If exposed, natural reflex to blink and turn his head enough to protect from the risk of injury.
3. Classe 3A: The output power is less than 5 mW, which limits the power reaching the retina to 1 mW when the pupil is dilated at maximum (estimated opening 7 mm).Therefore, the accidental exposure to a laser class 3A should not be more dangerous than exposure to a class 2 laser.
4. Classe 3B: The output power is less than 500 mW, sufficient to cause eye injuries that are described from a capacity of 150 MW
5. Classe 4: The output power exceeds 500 mW. These High Powered Laser Pointer can cause eye and skin damage and even cause inflammation of the objects on which they are directed.
