Developed the new BDX-3 product, Starveil ultra-thin cover glass for space applications

Nippon Electric Glass developed BDX-3, a new Starveil ultra-thin cover glass for space applications. The product suppresses radiation-induced coloration, reduces ultraviolet transmittance compared with the previous BDX-2, and supports use across a broad range of space environments, including medium and high orbits.
