39-420 12.7 mm Dia. Zinc Selenide Protective Flat Window; t=2mm BBAR 8-12µm

This 39-420 Zinc Selenide (ZnSe) Protective Flat Window, offered by Edmund Optics, is a high-quality optical component designed for a wide range of applications. The window boasts a diameter of 12.7 mm and a thickness of 2 mm, making it a compact yet robust solution for various optical systems.

The window is made from ZnSe, a material known for its excellent optical properties, including high transparency in the infrared region, making it ideal for applications such as thermal imaging and spectroscopy. The ZnSe material is also chemically stable and resistant to environmental factors, ensuring longevity and reliability in various operating conditions.

The window features a Broadband Anti-Reflective (BBAR) coating on both the front and back surfaces. This coating, specifically designed for the 8-12 µm wavelength range, significantly reduces surface reflections, thereby enhancing the overall transmission of the window. The BBAR coating ensures optimal performance in infrared applications, making this window a superior choice for such systems.

The window's geometry is that of a Thin Lens, which provides excellent optical performance while minimizing weight and bulk. This feature makes the window suitable for applications where space and weight are critical factors.
