532nm; Wavelength Range: 190-550nm; Standard Used: EN 207:2009 AC: 2011;
Certification: CE Certified; Package: 1 PCS protective goggles & 1 PCS
protective box. This is a graph of the relationship between wavelength and optical density
(light absorption value). Obviously, the absorption value of different
wavelengths is of course different. This glasses mainly protects the
wavelength of 190-550nm; Optical density is a complex characteristic of
materials that can slow down the propagation speed of light and produce
refraction (refraction) effects; Different lasers (and corresponding
wavelengths) have different impact on the human eye; Generally speaking,
the greater the optical density, the better the protective effect.
