25mm Dia., 0.21mm Thick, Chemically Strengthened SCHOTT AS 87 eco Ultra-Thin Window

Product Details Enhanced Impact, Temperature, and Scratch Resistance High Transmission in the Visible and NIR Spectra Ideal as Cover Glass for Displays and Sensors SCHOTT AS 87 eco Ultra-Thin Windows Also Available Chemically Strengthened SCHOTT AS 87 eco Ultra-Thin Windows feature enhanced mechanical properties, including impact, temperature, and scratch resistance. The ultra-thin substrates allow these windows to be used in low profile designs, enabling lighter, more compact optical systems. High transmission across the visible and NIR spectra coupled with excellent surface quality enables these windows to protect a range of sensors and display technologies on the market. Chemically Strengthened SCHOTT AS 87 eco Ultra-Thin Windows are ideal for use as cover glass where frequent surface contact or handling is expected, including displays, fingerprint sensors, and touch panels.
