Laser Pointer 20000mW
This 20000mW blue laser pointer is most powerful!
It was illuminated for 5 minutes, it was not blown up, and there was no black mark on the outer wall. Then, blow it to the maximum, and the balloon wall is thinner. Place the laser pointer one meter away from it, align it, turn it on, and the balloon will instantly explode.At this time, the balloon wall was thicker, and it was turned on.
Besides, in the promotional video of the store, the laser pointer can easily ignite matches and cigarettes. We also attempted to align it at a distance of 0.3 meters to a game, and for 5 minutes, it remained unlit. The reporter turned this information back to the merchant, and the merchant said that this might be a problem of insufficient laser power or inaccurate focus.
The national standard divides the laser pointer into low-to-high degrees according to the degree of harm: Class 1, Class 1M, Class 2, Class 2M, Class 3R, Class 3B, Class 4, in which the 20000mW laser in the toy should meet the Class 1 laser radiation power limit. The value requirement is no more than 0.4 mW. However, the reporter's laser pen page sold online showed that most of the product introductions did not indicate the power level. It is not advisable to purchase them as toy guns for children. Children should be informed about the dangers of radiation. Consumers who have purchased the relevant products should carefully check whether the laser radiation category is Class 1. For laser toys of more than Class 1, it is recommended to stop using them immediately.
When consumers purchase these devices for teaching or office use, it is best to buy products with laser radiation category 3R and below (laser power is not more than 5mW). For non-professional users, avoid obtaining Class 4 high-power laser pointers.
