Mobile devices rely on advanced optical components to enable precise filtering, guidance, and selection of light for a variety of sensing functions. By utilizing cutting-edge thin-film coatings and innovative optical designs, these components deliver exceptional wavelength selectivity, low noise, and high reliability essential for modern mobile sensors.
Materion’s precision thin-film coatings and optical components are engineered to optimize light management, enhance sensor performance, and support the miniaturization demands of modern smartphones and tablets.
COATINGS FOR SMARTPHONE CAMERAS
Achieving excellent image quality in high-definition smartphone cameras requires careful optical design and advanced coatings. Materion’s anti-reflective coatings reduce unwanted reflections and ghost images within camera modules, improving light transmission and image clarity. Our proven Iralin™ multi-layer AR coatings can be applied to camera cover glasses, lenses, and other optical surfaces. Additionally, our metallic mirror coatings such as Alflex™ and Silflex™ enable periscope-style telephoto lenses, delivering real optical zoom in compact smartphone designs.
COMPONENTS FOR 3D IMAGING AND WAFER-LEVEL OPTICS
Recent advances in wafer-scale manufacturing have enabled the integration of compact 3D camera modules for facial recognition and gesture control. Materion is the sole supplier of AR coatings that reliably adhere to epoxy-based, transparent resin materials used in wafer-scale lens production. Our coatings support Time-of-Flight (ToF) and 3D imaging sensors by providing high transmission in the illumination wavelength range and exceptional bandpass blocking to suppress ambient light, ensuring accurate depth sensing and facial recognition.
ADVANCED OPTICAL COATINGS FOR SENSOR PROTECTION AND PERFORMANCE
Materion’s capabilities include depositing and patterning electrically conductive coatings such as Chrome and Indium-Tin-Oxide (ITO). These coatings enable capacitive or resistive sensing electrodes integrated into optical paths, critical for touch and proximity sensors. In 3D imaging, conductive coatings help integrate sensing elements that detect mechanical damage to laser diffusers, minimizing risks from laser illumination and enhancing device safety.
