Eye Safety for Fiber Laser Engraving

A fiber laser that has an open bed system needs a little more thought put into safety. I am used to my CO2 lasers and their safety needs, one of which is eyeglasses to prevent the reflected beam from hurting my vision. With the CO2 lasers, a simple pair of protection glasses is a perfect and easy fix. I did not realize when looking into my fiber laser that the different wavelength also carried different requirements for eye safety.

I needed specialty glasses that are made to stop my specific fiber laser’s wavelength. I highly recommend buying the safety glasses from your laser supplier and not trying to shop around to save a few bucks. If the ones you buy online elsewhere are not properly rated for the laser you are running, you put your eye safety as well as your customers’ and employees’ eye safety at risk.
