Protective Goggle

Why is 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 eliiminate the Maximum Permissible Exposure(MPE).

How to get a suitable goggle?

To select the optimal 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 attenuationn completed.
