The price of high-power laser pointers
Hello, today I will briefly introduce a high-power laser pointer I just bought. First, high laser pointers are not cheap. When I first bought it, it was as expensive as or even more expensive than a laser flashlight. The second price returns to normal, but it is still not cheap You should know that 532nm303 is 100MW, while ordinary laser teaching aids only have 5MW 635-650nm ordinary 3A laser beam. This dynamic is relatively safe and will not cause harm even if it is directly affected by people. This is the game we played when we were young. The Laser pointer is now worth less than a dollar.

I bought a high output laser pointer. Lasers used in class IV lasers for continuous radiation (greater than 500MW) have the risk of carelessness and ignition. In fact, the domestic laser pointer is usually below 3a, sometimes even lower than 3B. Previous work: teach you to make laser guns. This is a real 3B laser. If radiation hits a person's eyes, it will damage his eyesight Previously, when garbage people recorded mixing, some even bought a 1.6W laser setter, even a 5W laser diode, and saw a 40W carbon dioxide laser. These lasers are terrible. They are level 4 lasers. The first can be easily cut on combustible media, and the second can even be used for baking. These lasers are still dangerous. In other words, using 303 laser pattern 100MW, students often report that it is so dazzling that it can't be viewed normally It's hard.
