Class 3B / IIIB Laser Pointer

Class 3B visible-beam lasers are medium powered, from 5 to 499 milliwatts. A Class 3B laser can cause eye injury. The more powerful the laser, the greater the chance of injury.

A Class 3B 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. This is unsafe and is illegal -- you could be arrested and jailed.

Always be aware of the beam location. Keep it away from people's eyes and heads. Watch out for reflected beams from glass and shiny surfaces. When outdoors, you must avoid aiming at or near aircraft.

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.
