11-869 50.8 mm Dia. Germanium Protective Flat Window; t=3 mm BBAR 3-12µm

This 11-869 optical window, sourced from Edmund Optics, is a circular flat window with a diameter of 50.8 mm and a thickness of 3 mm. It is made of Germanium burnett, a material known for its excellent transmission properties in the infrared region of the spectrum, specifically at a wavelength of 10600 nm.

The window features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, specifically the 'edm arcedgermanium31' coating. This coating is designed to minimize reflection and optimize transmission across a broad range of wavelengths, from 3 to 12 µm.

The window is shaped as a thin lens, making it suitable for a wide range of optical applications. It is currently in stock and available for immediate purchase, as indicated by its weblink status. For more information, users can refer to the provided weblink.
