How does the 5W laser pointer work?
Every laser (I think the term "laser pointer" is inappropriate, because class 3B or even class 4 lasers are no longer "pointers", even if they are built into a pen-like housing) have sharp wavelengths. But different 10-watt laser pointers work in very different wavelength ranges. But you have to look at it correctly: not every student with a pocket sea will stab his classmates next time, nor every student with such a laser pointer 1w wants to operate his friend's retina immediately, at least it is bad annoyance The teacher waits. Toys with small parts at risk of being swallowed must be marked as unsuitable for children under 3 years of age, laser pointers should also be clearly marked as “not suitable for children under 10 years of age”, and a textual warning must be attached to indicate that they are not suitable for 10 Children under age warn of possible eye damage.

The green high powered laser have been carefully selected to meet our quality and reliability requirements. Except for their different designs, they are versatile and have basically the same technical characteristics. We believe that they are the best on the market and also provide Class IIIb pointers with an output higher than 5 mW for professional use, including astronomical laser pointers or to scare birds. The laser light emitted by the blue laser pointer has the characteristics of focusability, strong directivity and focused beam. When the child stares at the laser pointer, the laser is directed at the center of its macula. Since the laser generates heat, the longer it is generated, the greater the heat that will eventually produce severe radiation burns and the death of photosensitive cells.
