CO₂ lasers operate at 10,600nm in the far-infrared region and are commonly used for engraving, cutting, surgical procedures, and industrial processing. Because this wavelength differs significantly from visible and near-infrared lasers, specialised laser safety glasses are required.

Protective eyewear for CO₂ lasers is designed specifically to attenuate far-infrared radiation. The filters used for these lasers differ considerably from those used for fiber lasers or diode lasers.

Many CO₂ laser safety glasses provide high optical density while maintaining practical visibility for machine operation and clinical work.

Before purchasing protective eyewear, confirm that the specifications clearly state protection at 10,600nm or the wavelength generated by your laser system.
