Protective Goggle

Why is a protective goggle necessary for industrial lasers? Industrial laser produces visible and invisible radiations ranging from 100nm to 1400nm. UV beams (100-400nm) can lead to corneal damage while infrared light (400-1400nm) can penetrate the lens and harm the retina, resulting in permanent damage. Although higher-wavelength lasers are usually deemed safe, higher-power lasers still pose a danger to the eyes. Goggles are specifically designed to safeguard against certain wavelengths, working to decrease laser intensity or eliminate the Maximum Permissible Exposure (MPE). How to get a suitable goggle? To select the optimal laser Goggle, consider Visual Laser Transmittance (VLT), applicable wavelengths and Optical Density (OD) values. VLT lower than 20% can cause reduced vision requiring extra lighting. OD determines the amount of light filtered and the higher the value, the more attenuation completed.
