Head-Up Displays (HUDs)
Driver assistance systems are becoming the norm in the automotive industry and is becoming ubiquitous in the industry. One type of assistance system is the Head-Up Display or HUD, which uses a series of projectors, cold mirrors and beamsplitters to project data onto an automobile’s or airplane’s windshield.
In a typical HUD, cold mirrors are used as the concave mirror. Cold mirrors reflect visible light and allow the transmission of infrared radiation. These mirrors are used at an angle of incidence of 45°, thus reducing the temperature load from a light source by heat-light separation, which is important for applications where the light source is in close proximity to the mirror like in a HUD.
EMF has supplied 700,000+ cold mirrors without a single incident of a field failure
A global Japanese automotive OEM components manufacturer was relying on native suppliers for many of the technical components – including the cold mirror – while maintaining assembly operations to the US. So, they decided to identify a US-based manufacturer of cold mirrors who could supply them cold mirrors in large volumes while maintaining the incredibly demanding delivery and quality requirements.
With 26 vacuum coating chambers and 40 million square inches of coating capacity, EMF developed a new coating technology designed to meet the rigorous specifications of the Japanese car manufacturer. EMF’s first round of product met all quality requirements and was competitively priced. Consequently, EMF won a large piece of business to supply cold mirrors for Head-Up Displays.
