Safety instructions for high-power laser pointers
High precision, high speed, fast execution, recoilless, green laser pointer, with its excellent performance, became famous in one fell swoop. However, the laser pointer is not a "one size fits all", the operating efficiency will be greatly reduced in bad weather, and the dust cloud may restrict the laser pointer. It is foreseeable that laser weapons will become a new attack method, which will have a major impact on the structure and tactics of future wars. Laser pointers are becoming more and more popular among astronomy enthusiasts. Astronomers all over the world add high-power lasers to their toolboxes, so I think I will spend time using laser pointers to provide safety instructions. Do not point the laser at or near strangers. This misuse will cause the bad image of the laser pointer crow. There is no doubt that in sports, the "laser animal wanted" for laser athletes is intended to stop the competition absurdly, which is unacceptable and illegal. It is this action that led the public to support the ban on the use of laser pointers.

The main use of lasers in astronomy and starry sky observation is to help identify constellations, stars and planets. Although complaints from federal authorities have increased, the aircraft claimed to be the target of illegal and irresponsible permit holders. Why should we deal with this particular accident? Lasers are inherently dangerous, but they are not at the end of this range. In the hands of responsible and capable people, the high-power high power laser pointer Crow is very safe and can be used for educational and entertainment purposes. Why does the laser hurt your eyes? For the eyes of people nearby, almost or all of the light passes through the pupils. The focused light is further focused by the lens to a sharp point on the retina (limited diffraction). According to the US Food and Drug Administration (FDA), as of April 2012, we have not received any reports of laser damage below 5 milliwatts. According to a test conducted by the National Institute of Standards and Technology (NIST) in 2013, if 44% of the tested green and red laser beams (122 laser tests in total) do not meet federal safety standards, it is approximately 90%. Even more worrying is that nearly half of the test pointers emit light beams that are twice the limit set by federal regulations. We take products and transparency seriously. Therefore, test each laser with a power meter to create a series of videos.
