What determines the color of the laser pointer?
The color of the laser beam is determined by the wavelength of the light emitted by the laser diode indicated in the laser pointer. Our Burning Laser Pointers only emits green light. Green light is the most obvious color of the human eye. This makes the beam of our laser pointer very bright, showing a spectacular bright green. On the other hand, the sloppy green laser pointer emits not only green light but also infrared light. Infrared rays can be seen by the human eye, so the beam of this inferior laser pointer is not bright enough and it is also very dangerous. As far as power is concerned, laser pointers and portable lasers will not let go of so much power. Especially when compared with ordinary 75W or 100W bulbs. What makes the laser so dangerous is that it has two unique characteristics.

The green laser pointer is now the most popular laser pointer in the world, because the green light beam is 6 times clearer than the red light beam, and the price is much cheaper than the blue-yellow beam. The user usually uses a green laser pointer. The emitted light green light pen has a wavelength of 532nm, the laser type is Class IIIA, and uses two AAA batteries. Brightness of the laser pointer green is more objective, so the eye risk is higher, the higher the performance, the more dangerous. Generally speaking, 5mW is widely used, and the US market can use 5mW laser pointers above 5mW through special approval. There are no strict domestic restrictions. We are required to pay special attention to the safety of users who are not facing the eyes or other dangerous areas, and to prevent the reflected laser light from entering the eyes.
