Protective Coating: All SunSensors® lenses are equipped with a hard coating for durability.
Anti-Reflection Coating: A multi-layer anti-reflective coating is recommended to enhance lens transparency in the clear state.
Darkening/Fading Curves: The document provides darkening and fading curves for SSS by Corning in both gray and brown under a solar simulator at 22°C with a thickness of 2 mm.
Transmission Curves: The lenses pass traffic signal recognition tests according to ISO 14889, ANSI Z80.3, and AS 1067.1 standards.
Optical Properties: The refractive index is 1.559, the Abbe number is 38, and the density is 1.17 g/cm3.
Transmission Factor: For visible light (380-780 nm), the transmission is 86% in the clear state and 17% in the dark state for gray lenses, and 85% and 20% respectively for brown lenses. UV-B transmission is less than 0.1% in both states for both colors. UV-A transmission is 5.0% in the clear state and 2.5% in the dark state for gray lenses, and 3.5% and 2.0% respectively for brown lenses.
Transmission Categories: According to ISO 8980-3, the transmission categories for SSS by Corning are 0 in the clear state and 3 for gray and 2 for brown in the dark state.
