Product Introduction — Chalcogenide glass has been widely used in the field of infrared optics due to its unique structure and properties. It offers excellent processing characteristics and enables the production of complex optical elements through precision molding technology.

Chalcogenide materials exhibit unique transmission characteristics in the spectral range of 1–16 µm. With high transmittance and a remarkably low temperature coefficient of refractive index (dn/dT), they are ideally suited as infrared materials for thermal imaging, sensing, and advanced optical systems. Their unique physical and chemical properties make chalcogenides the material of choice for next-generation infrared optics.

Precision glass molding (PGM) technology allows high-volume manufacturing of aspherical lenses, freeform surfaces, and complex lens arrays, contributing to lightweight, compact infrared modules with superior performance.
