As HMI (human machine interface), the windshield head-up display plays a special role in the Automotive segment. The driver can read relevant information off the windshield without looking away from the traffic situation. An efficient mirror system has to project this information from the PGU (picture-generating unit) into the driver’s field of vision in neutral colors and without any distortions and light losses. As one stop shop, Materion Balzers Optics offers all the necessary coated optical component: environmentally stable, color-neutral and high-reflectivity metallic and dielectric image-steering mirrors with optional AR coatings.
