Heliofold's ultra-thin cover glass protects spacecraft solar cells — high optical transmission, UV filtering, and proven radiation and atomic-oxygen durability, in a thinner, lighter package than conventional space glass.

It's built on a flight-proven protection route, so OEMs and integrators get a familiar integration path with real mass savings at the array level. Available in custom sizes and thicknesses, with technical coating options and cerium-doped formulations.
