39-409 25.4 mm Dia. Zinc Selenide Protective Flat Window; t=2mm BBAR 3-12µm

This 39-409 Zinc Selenide (ZnSe) Protective Flat Window is a high-quality optical component designed for a wide range of applications. Sourced from the reputable vendor Edmund Optics, this window boasts a 25.4 mm diameter and a thickness of 2 mm, making it a robust and reliable choice 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. This makes it particularly suitable for applications in the 3-12 µm wavelength range, as indicated by its BBAR (Broadband Anti-Reflection) coating. The BBAR coating on both the front and back surfaces further enhances the window's performance by reducing reflection and increasing transmission, thereby improving overall system efficiency.

The window's flat design ensures minimal distortion, making it ideal for applications requiring high-precision optical paths. Its 'Thin Lens' shape also contributes to its versatility, allowing it to be used in various optical configurations.
