It is organized in conjunction with the journal of this experiment, two sets of CCTV, "Is it true" column reports, the Burning Laser Pointers is high energy light when it shines on an object, the object, the energy of the light into heat, so that the surface temperature quickly rise to achieve ignition.
Experts point out that the public laser pointer itself is safe, but if it is misused, there is a significant security risk. In particular, some high power laser pointer, can ignite flammable or even fire. On some special occasions, 10000mw laser pointer is prohibited. Such as art galleries, zoos, etc. Therefore, in everyday life, do not irradiate with laser pointer on clothes, eyes, skin, and remember to let children play with a laser pointer.
very versatile green laser pointer
ultra powerful laser buy
Laser pointers can express reflected light spot or point of light and easy to carry objects, is widely used in all fields of life.Popular Rechargeable Laser Pointer wavelength colors red (650-660nm), green (532nm), blue (445-450nm) and light purple (405nm) and so on. Red laser pointers can be used indoors or in low light situations, and an uncomfortable hand indicating details. Green laser pointers can also be used outdoors in daylight or at longer distances. Tourists in the field can use to specify the target remotely in case of danger, use it to send a distress signal. Construction can be used to indicate a distance on construction sites.
Laser is dangerous to human health four degrees
It is understood that the human China current damage the laser divided into four degrees. The output power less than 0.4mW, 0.4mW two to one milliwatt, three between 1mW to 500mW, 200mw laser pointer four or more.If the output power greater than 0.4mW, can not have such direct eyes of laser irradiation. If the output power of three, it is easy to cause damage to the human eye. In addition, if the driver of the vehicle with 1000mw laser pointer radiation is irradiated people of vision is a brief case, he is likely to buy laser pointer
