Germanium Optical Windows
- Excellent for near-infrared and imaging applications.
- Anti-reflection coating with a wavelength range of 8 to 12 µm.
- This Window is ideal for low-power CO2 laser applications.
Germanium Optical Windows are highly valued in various optical applications due to their excellent transmission properties in the infrared (IR) spectrum. Made from high-quality germanium material, these optical windows provide superior clarity and durability. They are commonly used in systems like thermal imaging, infrared cameras, and sensor equipment, where reliable performance and precision are crucial. Germanium windows are ideal for use in environments with harsh conditions, offering resistance to thermal shock and moisture. These high-performance optical components are essential for industries such as defense, aerospace, and medical technology.
