Abstract
A glass sheet having a high near-IR transmission and very low visible transmission. The glass sheet is a silicate-type and has a composition that includes, in a content expressed as weight percentages, by total weight of glass: total iron (expressed as FeO) 0.02-1%, Chromium (expressed as CrO) 0.05-0.8%, Cobalt (expressed as Co) 0.03-0.175%. The glass sheet shows, intrinsically, a very low visible transmission together with a high IR transmission at wavelengths of interest (i.e. 850, 900 and 950 nm) and low amounts of Crspecies. The glass sheet is therefore valuable within the context of autonomous cars and in particular, those with fully integrating LiDAR systems.
