9MM laser head red laser diode laser diode laser diode

Description:
For a long time to light the laser head please increase the limiting resistance
1, the laser at any time can never point to themselves or others eyes, even if the laser in the closed case will have opened the possibility of error.
2, the laser can not irradiate any reflective surface or smooth surface, excellent laser reflection, on exposure to when the reflective surface will produce reflection, if exposure to human eyes can cause damage.
3, the laser is not a toy, do not give children intelligence is not complete, do not understand the laser characteristics of people, in this case, easily lead to injury.
4, the use of lasers should wear special goggles, the invisible laser, this is particularly important.
5, according to the laser can not vehicles, aircraft have transportation.
6, the laser should pay attention to the safety of the battery, to prevent others from removing the battery or battery explosion caused by short combustion.
Laser emission principle and special nature of the production process determines the characteristics of laser light that does not have a common: the Miyoshi (good monochromaticity, coherence, directionality) high (high intensity).
