Customers use a variety of purposes for customers with different purchasing purposes. Different laser pointer models are prepared to meet customer needs. Low-power models can meet the needs of children’s entertainment or teacher teaching. High-power models are generally used for site cutting. Even if I buy it, I only use it for collection. I shouldn’t take it out and fiddle with it. It hurts my skin.” Shi-Zheng has some concerns. Laser swords with higher sales power are mainly divided into blue light and green light. The color system and the two power levels of 1000 mW and 2000 mW, blue light is more irritating to the human body, and green light is more gentle. The higher the wattage, the stronger the heat accumulation and the more dangerous. Use safety first. We have Equipped with protective glasses, but it always hurts when it strikes people, ranging from a burning pain to severe skin damage. If you keep looking at the beam, you may experience dizziness or even nausea. The monochromaticity of the laser is better than ordinary light sources Many, in general, the laser can concentrate energy to a point, so you can think of the laser as very strong light. The damage caused by ordinary light can cause double the damage. For example, we feel warm in the sun, mainly The thermal effect caused by infrared rays in sunlight. So the red laser with a longer wavelength can cause serious burns. However, since the power of the laser pointer is generally small. The thermal effect is not strong, but the laser power used for industrial processing is enough to cause serious hurt.
Light is emitted from a light source to an object, and the scattered and reflected wavelengths are perceived by the eyes. Our brains say it is "green" when the wavelength is 500-570 nm, or it is "green" when it is 570 nm. "The wavelength is 610-780 nm. It recognizes it as "red". I tried to modify the laser pointer that can be purchased online. I fixed it to the air gun myself. Many cheap lasers are powerful and very dangerous, so you need to be careful when handling them. Just like the muzzle of an air gun, never point it at people or creatures, and don't look directly at yourself. Be careful not to look in the mirror. We are not responsible for any accidents caused by laser while imitating this video, please be sure to deal with it at your own risk.
