An optical element, which is transparent, for a motor vehicle, including at least one transparent first layer containing a polymer material and at least one second layer including at least silicon, titanium and oxygen. The optical element has a surface roughness defined by a mean square deviation Rq greater than or equal to 20 nm.

Optical element for a motor vehicle

A transparent optical element for a motor vehicle includes at least one first transparent layer of a polymer material. The optical element further has at least one second transparent layer including at least silicon, titanium, oxygen and nitrogen.

Transparent optical element for a motor vehicle

A method for moulding an optical component by a mould, at least one moulding station, and at least one cooling station including a cooling space, the method including: a step of moulding a moulded component in a moulding station, a step of transferring this component from this moulding station into the cooling space, keeping the moulded component facing at least one of the mould parts, a step of cooling the moulded component by sending a cooling fluid between the moulded component and the walls of the cooling space, the moulded component being kept some distance from these walls.

Method for moulding an optical component with the component being directly cooled by a fluid

An optical assembly of a light-emitting module, especially of a lighting and/or signalling module, for a motor vehicle, including an optical element, a frame; the optical element being overmoulded on the frame, the frame being shaped so as to make a mechanical attachment between the frame and the optical element following the overmoulding of the optical element on the frame.
