CAUTION:
Never look directly into the path of a laser beam. Laser protection eyewear offers protection against accidental exposure to stray or diffused reflection of laser beam energy for a maximum exposure of 5 seconds. Laser protection eyewear protects only the wearer. All personnel within the work area should wear appropriate eye protection against possible exposure to reflected beam energy. Increased work area lighting may be required if eye protection luminous transmission is less than 20%.

All information is without guarantee. In case of doubt, please contact your laser protection officer.
