Phosio

Phosio Corporation is a materials science startup based in Corvallis, Oregon, that develops UV-curable metal oxide precursors (PhosioLux®) enabling high-performance, low-cost optical coatings for augmented reality eyewear and next-generation displays. The company's breakthrough process cuts production time by up to 100x and reduces costs by up to 90% compared to traditional vapor deposition methods, with materials compatible with spin coating and slot die coating on flexible, lightweight substrates. Founded in 2018 and based at Oregon State University's Advanced Technology and Manufacturing Institute (ATAMI), Phosio targets AR/AI smart glasses manufacturers, semiconductor fabs, and display makers with tunable refractive index coatings (n = 1.20 to 2.60) that enable smaller, lighter, higher-performance wearable devices.
