Nd:YAG lasers are among the most widely used laser systems in medical, scientific, and industrial applications. These lasers typically operate at 1064nm, which lies within the near-infrared spectrum.

Infrared wavelengths are not visible to the human eye, which can make them particularly important to manage from a safety perspective. Laser safety glasses designed for 1064nm systems contain specialised filters that attenuate radiation within this wavelength range.

Optical density ratings are used to indicate how effectively the lenses reduce laser energy. Depending on the power of the laser system, higher OD values may be required.

Nd:YAG lasers are used in a variety of applications including medical procedures, laser marking, material processing, and laboratory research.

Protective eyewear designed for the correct wavelength range helps reduce exposure to infrared radiation when working with these laser systems.
