The Infrared Germanium window is widely used optical components designed for applications in the mid-infrared (IR) spectrum.
With excellent transmission from 2 μm to 14 μm, germanium window is a preferred choice for infrared imaging, thermal cameras, and spectroscopy systems.
Its high refractive index and durability make them one of the most important materials in IR optics.
Key Features of Germanium Windows
- Broad IR Transmission Range: 2 – 14 μm, ideal for mid-infrared applications.
- High Refractive Index: ~4.0, providing superior focusing power.
- Excellent Thermal Properties: Stable performance in demanding environments.
- Durability: Resistant to environmental exposure and mechanical stress.
- Customizable Options: Available in different diameters, thicknesses, and with AR coatings.
Applications of Infrared Germanium Windows
- Thermal Imaging Systems – People often use the windows in defense, surveillance, and security cameras.
- Spectroscopy – It enhances performance in infrared spectroscopic instruments.
- Medical Equipment – T diagnostic and therapeutic infrared devices need the windows.
- Industrial Lasers – Suitable for CO₂ laser optics and infrared sensors.
Why Choose Germanium Window?
Compared with common windows, Germanium window offers higher refractive index and better mechanical strength.
However, it has a relatively high density and is not suitable for applications requiring weight-sensitive optics.
With anti-reflective coatings, germanium windows provide excellent transmission efficiency and reduced reflection loss.
