Laser lights, I believe many people are aware of them. While they bring us colorful colors, they also bring us some hazards. So what are the hazards of laser lights? Next, let’s take a look at the following introduction to the hazards of laser lights!
Laser lights that are harmful to laser lights are generally divided into industrial laser lights and entertainment laser lights. Laser lights have the advantages of bright colors, high brightness, good directivity, long range, and easy control, making them look more magical and dreamy. Used in buildings, parks, squares, theaters, etc., the non-divergent nature of laser beams can attract the attention of people from several kilometers away, because the point where the laser emits has also become the focus of people's attention. However, although the laser light show is beautiful, you must remember not to watch it for a long time, because looking at the laser light for a long time will cause great damage to your eyes.
Lasers that are harmful to laser lights are also light, but they are brighter and have good parallelism. The damage to human eyes comes from these two points. The most critical thing is parallelism. Our eyes are also a lens imaging system like a camera. When parallel light enters the eye, as long as we are not looking at a very close object at the time, the light beam will be concentrated to a point on the retina. The laser is already very bright, but if it is focused again, it will burn the retina.
Hazards of laser lights. Use a piece of paper to block the laser power meter, leaving only a small hole with a diameter of about 3 mm. I went out around noon to measure the power of the sun, and there was no response at the most sensitive setting. , that is to say, when the diameter of sunlight is 3 mm, it is not even 0.1 milliwatts. Lasers are often tens or hundreds of milliwatts.
Hazards of laser lights: Green laser lights commonly used in stage lighting can cause damage to human eyes. Low-power lasers emitted by stage lasers can cause cumulative damage to human eyes, and most of them are irreversible. Don't look too far. Even a laser pointer with a power of no more than 5 milliwatts is still harmful to people.
