Crossbow Lens Laser Lpl-b

The LPL-B Lens technology is designed to block non-visible InfraRed lasers from damaging the wearers eyes. ESS LPL-B lenses protect against non-visible IR lasers at 820-1090nm (4.0 OD) and 1064nm (5.0 OD), visible violet lasers at 405nm wavelength (5.0 OD), and visible blue lasers at 445nm wavelength (4.0 OD). At a VLT of 57% photopic (daytime) and 42% scotopic (nighttime) this allows for optimum protection and operation versatility in both bright and low light conditions.
