For use by personnel, do not have to buy the Class 3B and Class 4 high-power blue laser pointers. Three is not a toy for children to use to buy a laser pointer. Children should be knowledgeable about laser radiation risks that prevent children from buying high power laser pointers in schools around the vendors, stores, internet and other channels. For the office or teaching laser pointer should be placed where the children cannot reach. Fourth, when consumers buy toy guns for children by using packaging, try the product or contact a sales representative to see if the laser pointer 5000mw.

Advises consumers not to buy toys with laser sighting functions or functions for children. When purchased related products, should carefully check whether the category of laser radiation class 1, class 1 laser over immediately the use of the toy is recommended. Fifth, consumers should use a 1000mw laser pointer in the correct operation, avoiding laser exposure to human eyes, skin and clothing and other places.

First, try to choose a formal channels to buy a laser pointer, children's laser gun, no laser radiation class information, non-brand models without warnings and should avoid purchase. Second, the academic or office consumer when using a 3000mw laser pointer, you should carefully read the product specifications of the laser, the best purchase category for class 3R laser radiation and the following product (laser power less than 5 mW).

Do you think your blue laser pointer is the strongest?

Wu Cheng said, It is clear that the laser by stimulated emission of the laser beam, the intensity of the reflected laser radiation power of the laser radiation power is too high, the body will cause photochemical damage and thermal damage still in the developmental phase, especially for children when that Eye and skin by 5000mw laser pointer blue can cause more serious consequences. Wu introduced in laser vision damage and its intensity proportional to the exposure time, the maximum green 500mW laser pointern, the longer the exposure time, the more severe optical damage. Why do your eyes burn?

This laser pointer blue extremely strong is simply great

WU Cheng explains, “Laser is a highly pure, highly concentrated light energy, when the laser hit the eyes, through retinal pigment epithelium is black, it will instantly absorb light energy into producing thermal effects when the laser is on. the macular region, it will lead to macular cone damage, severe macula will burn out. after the death of photoreceptor cells burned, the equivalent of photo negative broken lens of the camera is defective (the cornea), also can be changed, but the film is broken, according to the current science and technology, it is not possible to fix. " Wu to remind the public: do not use a 2000mW blue laser pointer as a toy for children to buy, children should know about laser radiation risks that prevent children from buying high power laser pointer in the Schools around the providers, shops, internet and other channels.
