40mm Dia., 0.4mm Thick, SCHOTT D263 T eco Window

Product Details Thin 0.4mm SCHOTT D263 T eco Substrates Excellent Glass Alternative to Plastic Optics Ideal for Weight and Space Sensitive Applications SCHOTT D263 T eco Windows feature thin 0.4mm thick, eco-friendly manufactured glass substrates with high transmission in the visible and near-infrared (NIR) spectra. These windows are manufactured through a precision down-draw manufacturing process, achieving surface roughness <1nm RMS with excellent thickness tolerances and low total thickness variation (TTV). SCHOTT D263 T eco glass has high chemical resistance and environmental durability and is an excellent alternative to plastic in automotive and electronics applications requiring lightweight optics. SCHOTT D263 T eco Windows are ideal for use as cover glass for resistive touch panels, substrates for capacitive touch sensors, or as substrates for optical filters used in mobile devices or LiDAR units.
