11-867 76.2 mm Dia. Germanium Protective Flat Window; t=5 mm BBAR 3-5µm

This 11-867 optical window, sourced from Edmund Optics, boasts a generous 76.2 mm diameter and a thickness of 5 mm, making it a robust and reliable choice for various optical applications. The window is fabricated from Germanium Burnett, a material known for its excellent transmission properties in the infrared region of the spectrum, particularly between 2-14 µm.

The window features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, specifically the EDM ArcEGermanium35 coating. This coating is designed to minimize reflection losses across a broad spectrum, typically from 3-5 µm. The result is enhanced transmission of light through the window, reducing the need for additional corrective elements and improving overall system performance.

The window's flat geometry ensures minimal distortion, making it suitable for use in imaging systems, beam delivery, and other applications where optical quality is paramount. The thin lens shape further enhances its usability, allowing for easy integration into existing optical systems.
