Knowledge of laser pointer safety Lasers have been a controversial topic since it was first created in the world. All people pay close attention to the dangers of lasers and the safety of laser operation. Given general knowledge of laser safety, the dangers of lasers are no longer as terrible as we thought. Lasers are an integral part of optics, science, laboratory experiments, military and medical applications. Not only the most powerful and portable lasers that are readily available, but more and more industrial lasers are needed to bring about high-tech, more convenient and superior processes. development of. This is the result and fact of modern high-tech development, and no one can prevent this intent. With the widespread use of lasers around us, laser safety has become an important point for everyone who can keep in touch with it. If you have an astronomical laser pointer, do not stare at the laser beam or spot, or attempt to abuse the laser pointer recommendation unless you are authorized to do so. Laser radiation causes damage mainly due to the thermal effect. The relatively low amount of laser light can lead to permanent eye injury. For example, medium and high power lasers are potentially dangerous because they can burn the retina of the eye and even the skin. Low-power lasers of less than 50 mW do not pose a danger to human eyes or skin when viewed or stared directly. レーザーポインター https://www.flashraito.com/laserpen_1000mw/p-1227.html レーザーポインター最強 https://www.flashraito.com/laserpen_1000mw/p-7121.html レーザーポインターカラス https://www.flashraito.com/laserpen_500mw/p-7056.html レーザーポインターおすすめ https://www.flashraito.com/laserpen_200mw/p-1141.html A laser that is powerful enough in visible light can penetrate the eyeball and cause heating of the retina. Infrared lasers are especially dangerous because the human eye has no reaction or reaction to the invisible beam. Exposure to high-power infrared lasers does not cause pain or immediate loss of vision. Severe retinal damage can occur without signs. The following guidelines provide knowledge about the safety of laser pointer crows. ● Minorities should prohibit individual possession or use of lasers without supervision. Not knowing the risks of lasers should always be ignored. It's no joke, but you need to be especially careful with invisible infrared laser pointers. ● Everyone who lifts a laser pointer up to 50mW always needs proper eye protection. The use of high power lasers can cause thermal damage to the human eye. A pair of laser safety goggles is always a must for owners of high power lasers. ● Pointing and reflection of laser light can be dangerous to the human eye. Do not stare at the laser or point at aircraft, moving vehicles, human or animal eyes or skin.
