Germanium shielding window

Germanium protective windows are a critical component in infrared optical systems, characterized by the following features: 1. High infrared transmittance: They exhibit excellent transmission performance in the 2-12μm wavelength band (particularly the 8-14μm long-wave infrared band), efficiently transmitting infrared signals. This makes them suitable for applications such as thermal imaging and infrared temperature measurement. 2. Physical protection function: Germanium material has high hardness and strong wear resistance, protecting internal optical components from environmental factors like dust, sand, and mechanical impacts, ensuring stable system operation. 3. Environmental adaptability: They possess good thermal shock resistance and chemical stability, maintaining performance across a wide temperature range (e.g., -40°C to +70°C) and harsh environments (e.g., high humidity, salt spray). 4. Customizability: They can be customized to different sizes, thicknesses, and coating schemes according to requirements. For example, anti-reflective coatings or diamond-like carbon (DLC) films
