Chalcogenide Materials

Chalcogenide Materials

Chalcogenide materials have a wide transmission range from 0.5μm to 25μm, low refractive index temperature coefficient, low dispersion, and versatile glass compositions.  These materials allow higher production efficiency by lowering production costs and consumption of scarce resources like Germanium and can be manufactured in batches using precision moulding technology.
