83-348 12.5 mm Dia. Germanium Protective Flat Window; t=3 mm BBAR 3-12µm

This 83-348 optical window, sourced from Edmund Optics, is a circular, flat window with a diameter of 12.5 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, making it ideal for applications in this range.

The window features a broadband anti-reflection (BBAR) coating on both the front and back surfaces, specifically the 'edm arcedgermanium31' coating. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the window in its intended application. The BBAR coating is effective over a wide wavelength range, from 3 to 12 µm.

The window is shaped as a thin lens, which may provide some focusing or collimating properties, depending on the specific application. However, its primary function is to protect optical elements from environmental contaminants and damage, while minimally affecting the light passing through it.
