Abstract
A glass sheet of silicate-type showing intrinsically a very low visible transmission with high IR transmission at wavelengths of interest (i.e., 850, 900 and 950 nm), and low amounts of Cr6+ species, valuable within the context of autonomous cars, and in particular those fully integrating LiDAR systems. The glass sheet having a composition in a content expressed as weight percentages, by total weight of glass:
