Fiber lasers are commonly used in manufacturing processes such as cutting, welding, marking, and engraving. These systems often operate at wavelengths near 1064nm, placing them within the infrared spectrum.

Because fiber lasers can generate high levels of concentrated energy, selecting protective eyewear designed for these wavelengths is an important part of laser safety.

Laser safety glasses for fiber lasers typically contain filters engineered to attenuate near-infrared radiation. The performance of these filters is indicated by optical density ratings, which describe how effectively the lens reduces laser energy.

Higher optical density levels may be required depending on the power of the laser system and the working environment.

Protective eyewear is typically used alongside additional controls such as shielding, controlled access areas, and operational procedures.

Understanding the wavelength and power characteristics of fiber lasers helps ensure appropriate laser safety eyewear is selected.
