wavelengths of laser eye injury site

But minimum irradiation distance of 13cm, the maximum exposure time of ten seconds the following for safety. IIIB typical applications such as laser spectroscopy and entertainment lighting show. ClassIV: high-output continuous-wave (greater than 500mW), higher than the third level, there is a fire hazard, diffuse reflection also at risk. Typical applications such as surgery, research, cutting, welding and micro-mechanical processing. Although the laser safety levels have been defined, but for the human body, especially the human eye, the damage is different at different wavelengths, and therefore, although two or three of the laser, the same should be noted. More customers order more infrared  laser pointer .
Different wavelengths of laser eye injury site, the wavelength partition wavelength range (nm) primary site of injury, 180-400 UV laser cornea, lens, visible laser 400-700 retina, choroid, near-infrared laser 700-1400 retina, choroid, lens, in Far-infrared laser 1400-106 cornea, the laser operating environment in the long-term workers in the eyes by long-term effects. In operation and use of lasers, even if not directly by the laser irradiation, resulting in injury accidents. However, the anti-out laser rays through walls or other objects produced by micro-reflections, long-term work in this environment of people, a high incidence of cataracts. Prolonged exposure to green laser light, especially when the laser pointer over 5 mW of power, just a few seconds may cause functional vision of the human eye damage. The company needs to purchase more infrared  laser pointer .
Before the eyes of my colleagues once smashed by the laser. The results gave the company lost a little money. The key is self-inflicted injury, loss is difficult to estimate. Especially for industrial processing lasers are now engaged in those who are even more so. The safety level of laser processing are generally four (most dangerous), and now there are many applications of laser is not visible in the scope, the more light that is not visible, the more dangerous.
