CE-certified LaserShields meet the US and international laser safety standards, including ANSI Z136.1, EN207 | EN208 | EN60825 and Z87.1.
The level of protection is based on the optical density factor as follows:
190 – 430nm: OD 5+
525 – 532nm: OD 1.5+
632 – 659nm: OD 1.4+
640 – 650nm: OD 2.5+
MLA type offers the most protection in the blue and red spectrum.
