Abstract
A silicate-type glass sheet that includes 0.002-1.1% total iron (expressed as FeO), greater than or equal to 0.005% manganese (expressed as MnO), and optionally 0-1.3% chromium (expressed as CrO). The sum of the contents of total iron, manganese, and chromium, expressed as weight percentages are greater than or equal to 1% of the total weight of the glass. The ratios R1, defined as FeO*/(49+0.43(CrO*—MnO*)), and R2, defined as FeO*/(34+0.3(CrO*—MnO*)), both being less than 1. FeO*, MnO* and CrO* represent the relative percentages with respect to the sum of (FeO+MnO+CrO). Such a glass sheet shows a very low visible transmission together with high IR transmission in the region 1000-2000 nm, especially at wavelengths of interest between 1050 and 1550 nm, thereby valuable within the context of autonomous cars, in particular those fully integrating LiDAR systems.
