405nm 445nm 450nm Blue 808NM 980NM IR Laser Eye Glasses

405nm 445nm 450nm Blue 808NM 980NM IR Laser Protection Glasses Goggles OD4+ -- Laser protective glasses with light absorption principle: its light is not selective, it is safe PROTECTION diffuse light; incident angle of the light source is not selective, specific bands can be full protection of the laser and the light, the light and rapid response, decay rate is higher, the surface afraid of wear, even with scratch, does not affect the light security. Specifications Protection Features: All-round absorption Protection Wavelength: 200-540nm Visible Light Transmittance: 60% Optical Density: OD 4+ T(405nm-450nm)=15% Size:145x110x45mm Suitable For: Quadruple-frequency Nd: YAG laser / excimer laser He-cd / YAG laser / semiconductor laser Packing Included 1 x Laser Protection Glasses
