Green Star Laser Pointer 10mW just belongs to Class IIIa laser. According to special technology of APC automatic output power control system, this special laser pointer just gets highly stable output power and constant brightness green laser beam in all working places.
Once the operating temperature is extremely higher than expected, the APC green laser pointer begins self protection, stop green laser beam emission so as to make best protection of the internal part perfectly. Even though sometimes 5mW green laser pointer is being used long term continuously, however, users always have no need to worry about its laser beam stability.

5mW APC laser engraving machine gets the same appearance with common laser. However, according to its special design of constant power and constant current design, this special laser device is always able to make great work in all kinds of high tech working fields. Whatever kind of industrial laser dot projection work, this green laser pointer is able to supply users the most stable green laser beam source.

Even though sometimes the laser pointers output power is much higher than its designed, however, the electric driving circuit can automatically reduce 200mW Red Laser Module output power supply for its 532nm green DPSS laser part. This special APC technology just protect the internal part of green laser pointer with constant 5mW output power supply. In all kind of working occasions, green laser pointer itself always makes perfect protection from outside working conditions.

Pilots with Med-Flight II, a program of the Virginia State Police for which Wellmont provides the medical care team, have also been subjected to High power green laser pointers in recent years.Sgt. John Ratliff said Med-Flight II pilots are less likely to be confronted with this situation because they do not spend as much time in more urban areas than WellmontOne, but he said it remains a dangerous safety issue for the crew on that helicopter. He estimated laser pointers have been shined on Med-Flight II helicopters about 10 times in the last five years.

The tail cap can be screw off, and then insert 2 pieces of AAA alkaline batteries. Usually each two pieces of batteries can support at least 180 seconds continuous green laser beam emissions. Even though it only gets very low output power of 5mW, however, it just passes through quite strict inspection from FDA safety approval and CE certification. As a result, in the following operation of this Class IIIa green laser pointer, it always makes upper nice performance.

Perry and Ratliff said the situation is exacerbated when pilots and other personnel on the helicopter are wearing night-vision goggles, which are designed to help them see better in the dark. These goggles increase the intensity of the blinding light, they said.
