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.

A detection device with an optical device comprising at least one light source and at least one light sensitive element optically decoupled inside the detection device. A protective housing encloses the optical device. An optical cover comprising an internal surface facing the optical device and an external surface opposite to the internal surface, wherein the optical cover is transparent at the operating wavelength of the optical device, and comprises at least two separate apertures. A first aperture faces the light source and a second aperture faces the light sensitive element. The optical cover is one piece comprised of diffusing, absorbing, multilayer elements, and/or wavelength-changing elements placed between the first and second apertures in an optical decoupling zone outside the field of view of the light source and the sensitive element to avoid the stray light travelling from the light source to the sensitive element within the optical cover.
