Is there a difference in the power of a 505nm laser pointer?
In the classification system,.300MW green laser net sales, although some labeled as minority, but did not say specific use reporter noticed, some high powered laser pen sales are who? Class 1 product laser said 3A ", is a class 1 laser, some products belong to the "class" or "3B" class, but also very few, there are "4B". According to GB7247 laser safety standard radiation protection requirements, class 1 2, laser 3A low, laser 3B, high power laser 4. GB suggests that above 3A laser record, "laser safety officer should be designated" and provide the opportunity to need, especially for users of level 4 laser products wearing safety glasses and protective clothing. So laser Pointers are good. - Beyond toys. "The 532nm laser pointer is therefore likely to be the murder weapon, and he should be able to buy it, not buy it.

The principle of the laser was discovered by the famous American physicist Albert Einstein in 1916, but it was not until 1960 that the first laser was successfully manufactured. It has been called the fastest knife, the most accurate ruler, the brightest light and the magic laser. Laser driver is an important part of laser generation. Physical lasers represent light amplification by radiation stimulation. In addition, it will be an excellent navigation tool when you travel. It's a good tool for pointing to distant targets or stars and signaling for help. Moreover, the laser pointer is made of high-quality materials and is durable.
