The article evaluates developments in moulded optical plastics components for automotive use instead of conventional moulded glass. Optical thermoplastics such as acrylic and polycarbonate offer low weight (about 50% compared with glass) and resistance to shattering. Moulded plastics also offer freedom of shape allowing optical systems impossible in glass. Recent applications for plastics components include moulded instrument panels, which include light guides for displays, and also rearview mirrors moulded to curves of diminishing radius to give undistorted all-round vision. Future applications discussed include cheaper head-up displays, windows and also rearview displays. (TRRL)
