Laser pointers of various colors
First, let's talk about the maximum power issue. Let's briefly explain the maximum power limit of various colors of laser pointers. The maximum power of blue light will not exceed 5000mw, the maximum power of green will be 1000mw, and the maximum power of red and purple will not exceed 500mw. From this point, the possibility of excessively exaggerating the power of high-power high powered laser pointers in the market, such as blue 30000mw, green light 5000mw, etc., can be ruled out. This is impossible. Why is it impossible? Because of production technology and energy supply, you can imagine how 2 x 16340 batteries can generate 30,000mw of power? How does a single 18650 battery reach a power of 5000mw?

I don't want to put pressure on every finger, so I will introduce some tips so that you can enjoy the laser with confidence. Green lasers are very popular these days, especially by astronomers and astronomers. The green laser emits a light beam with a wavelength of 532 nanometers, and the measured value of the red laser beam is 630 nanometers. As you may know, green lasers are much more powerful and are generally classified as Class 3a lasers in the United States because they measure less than 5 milliwatts. However, please pay attention to label permissions.
