Abstract
A laminated vehicle glazing, suitable for use with an optical sensor (for example a LIDAR type sensor), comprises first and second plies of glazing material joined together by a ply of interlayer material between them, and either: a) the first ply is a pane of body-tinted glass having a colorant portion consisting of 0.70 to 1.00% by weight total iron (calculated as Fe2O3), 0 to 1.0% titania and 0 to 2.0% ceria, such that the glazing has a transmittance of at least 30% in the wavelength range 400 to 2100 nm, or b) the first ply of glazing material is a pane of body-tinted glass having a colorant portion consisting of 0.30 to 0.80 by weight total iron (calculated as Fe2O3), 0 to 1.0% titania (calculated as TiO2) and 0 to 2.0% ceria (calculated as CeO2), and the ply of interlayer material is a solar (IR) absorbing material, such that the glazing has a transmittance of at least 30% in the wavelength range 750 to 1300 nm.
