Germanium (Ge) Windows & Plates

Germanium Windows & Plates – Uncoated, AR/AR & AR/DLC Coated

Germanium Windows with excellent transmission across 2-14 µm waveband and can be used in both mid-wave infrared (IR) and long wave IR systems. Germanium is a widely used material for IR windows and lenses in thermal imaging systems.

This high density window has a thermal escape which makes the transmission reduce as the temperature of the window increases. Germanium Windows are commonly used in industrial/domestic CCTV cameras and aerospace industries, life and medical sciences, industrial OEM and many other infrared applications.
