Buying a green laser pointer seems simple. After all, you can think of it as just a pointing device. However, the green laser pointer only works if you consider it during the purchase process. After all, you don't want a green laser pointer that's barely visible to the naked eye. If you use this green laser pointer for a demonstration, you want your audience to be able to easily track your views. This is why it is important to consider the output power of the green laser designator when checking the lumens and candlelight produced by the designator. It's also important to keep this in mind when choosing laser Pointers of other colors.
Lasers come in visible and invisible (infrared or ultraviolet) forms. Visible lasers, like all visible light, produce a variety of wavelengths that determine the colors we actually see. Because there's a range of colors, from very dark to very bright, even ultraviolet and infrared. The standard 532nm green laser is always the brightest color to the human eye at the same power output. The laser power is measured in milliwatts (mW), ranging from 5 mW to 1000 mW (1W), in the shape of an outstretched hand. How much power should you use? It depends on which applications you are using the laser for. If you are looking for engraving lasers that can light matches and pop balloons, you need to purchase a 200MW laser minimum power (all colors), the higher the output power, the higher the burning power of any laser.
