Abstract
A head-up display system includes a projector configured for emitting a first ray of light having a first intensity, and a lens having a first surface facing the projector and a second surface spaced apart from the first surface. The lens is configured for refracting the first ray of light to emit from the second surface a second ray of light having a second intensity that is less than the first intensity, and a third ray of light that is parallel to the second ray of light and has a third intensity that is less than the second intensity. The system also includes a cured film disposed on the first surface and formed from an anti-reflection coating composition, wherein the cured film is configured for minimizing the third intensity. A device includes a windshield, an operator eyebox spaced apart from the windshield, and the head-up display system.
