This infrared laser pointer essentially consists of a laser diode, a control unit and power supply, consisting of a small laser generator. The use mainly of the power of the laser diode to produce a single wavelength excitation resonator beam, that is, laser pointer strength. For lasers, the power is a measure of the release of an important indicator of energy within the unit of time. Laser pointer is usually available in the market, their power range from a few milliwatts to several hundred milliwatts 00.00. The higher the current, the more energy per unit time of the laser output unit. Under normal circumstances, the body can withstand the laser power of 0.4 mW, high power laser pointer beam on the eyes can lead to retinal damage and can even lead to permanent vision loss. Prolonged direct contact with the skin can cause burns.
Why is an infrared laser pointer not visible?
It is understood that this year's CCTV 3.15 evening experts have a power of 5000mw laser pointer Infraot, laser emission opened the moment a dozen balloons were carried. Laser pointers against dark clothing took a while, and found a hole to appear in the clothing. The infrared laser pointer shines on a match head, not for a while, bursting into a flame.
March this year, AQSIQ issued a “50mw laser pointer, laser gun child product quality and consumer safety risk warning prompt,” said the children should not be used as toys to buy a blue laser pointer, consumers should avoid using the laser pointer illuminates the human eye, Skin and clothing and other places.

AQSIQ remind consumers to buy toy guns for children by checking the packaging, trying products, or checking with a seller to see if the toy laser confirms. Advises consumers not to buy toys with green laser sighting gun laser shooting feature or features for children. When buying related products, you should carefully consider whether the laser radiation category-level, laser toys more than one suggestion, stop immediately.
