Ultra-Durable CaLa?S? IR Windows for Aerospace & Defense

[Category : - CHEMISTRY]
[Viewed 70 times]

This patent presents a high-performance Calcium Lanthanum Sulfide (CaLa?S?) IR optical material that offers exceptional mechanical strength, erosion resistance, and IR transparency (2–16?m range). The self-propagating low-temperature synthesis (SPLTS) process enables rapid fabrication, while advanced sintering methods ensure a high-density, impact-resistant structure. Designed for missile domes, fighter jets, and forward-looking infrared (FLIR) systems, this technology provides a cost-effective, scalable alternative to ZnS and Germanium-based optics.
