Optical Materials

Sheldahl’s optical materials push the limits of possibility for optical performance through transparent conductive coatings designed to ensure the clarity, performance, and durability that demanding designs call for. The company offers several indium tin oxide (ITO) and PEDOT-based solutions engineered to meet specific optical, mechanical, and electrical requirements across a range of applications, including capacitive touch sensors, flexible displays, wearable devices, and solar cells. Patterned ITO and PEDOT films combine high flexibility with low electrical resistance, enabling precise, repeatable performance in optically demanding designs where transparency, conductivity, and mechanical durability must be balanced. These optical materials share Sheldahl’s core electronic materials manufacturing base, including vacuum deposition and precision coating processes, allowing tight control over film thickness and conductive uniformity across production runs. Applications include next-generation touch interfaces, flexible and foldable display technology, wearable electronics requiring transparent circuitry, and thin-film photovoltaic solar cell construction, all of which demand materials that are simultaneously optically clear, electrically conductive, and mechanically robust under repeated flexing.
