PRODUCT OVERVIEW
Introduction
Germanium windows are made from optical-grade germanium, a high-index infrared material widely used in long-wave infrared optical systems. Its strong transmission in the LWIR region and high refractive index give germanium a distinct role in infrared optical designs where compact geometry and controlled light propagation are important.
Unlike broadband materials that also transmit visible light, germanium is primarily valued for its infrared performance. Its combination of high optical density, good mechanical stability, and compatibility with precision infrared coatings makes it well suited to demanding thermal and sensing optics.
Applications
- Thermal camera protective windows
- Infrared sensor and detector windows
- LWIR surveillance system windows
- Infrared spectroscopy windows
Features & advantages
