64-380 75 mm Dia. Germanium Protective Flat Window; t=5 mm BBAR 3-12µm
The 64-380 is a 75 mm diameter, 5 mm thick Germanium Flat Window, designed for protective applications. This window is sourced from Edmund Optics and is currently in stock, as indicated by its weblink status.
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 center wavelength of 10600 nm.
The window features a Broadband Anti-Reflective (BBAR) coating on both the front and back surfaces. This coating, identified as 'edm arcedgermanium31', is specifically designed to reduce reflection and increase transmission across the 3-12 µm wavelength range.
The window is shaped as a Thin Lens, which may provide some focusing capabilities, depending on the application. However, its primary function is to protect optical elements from environmental hazards, such as dust, dirt, and moisture.
