83-352 50 mm Dia. Germanium Protective Flat Window; t=2 mm BBAR 3-12µm

The 83-352 is a 50 mm diameter, 2 mm thick Germanium Flat Window, designed and manufactured by Edmund Optics. This protective window boasts a Base Shape of Circular geometry, making it suitable for a wide range of optical applications.

The window is made from Germanium burnett, a material known for its excellent transmission properties in the infrared region of the spectrum. Specifically, this window is designed for use with a wavelength of 10600 nm, making it ideal for applications such as thermal imaging, spectroscopy, and other infrared-based technologies.

The 83-352 is coated with a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces. This coating, identified as 'edm arcedgermanium31', is designed to reduce reflection and increase transmission across the 3-12 µm spectral range. The result is improved image quality and system performance.

The window is shaped as a Thin Lens, which can be beneficial in certain optical systems where minimal optical path differences are required. The window's thin design also minimizes weight and potential distortions caused by thicker windows.
