48-857 75 mm Dia. Germanium Protective Flat Window; t=5 mm BBAR 8-12µm

This 75 mm diameter Germanium Protective Flat Window, with a thickness of 5 mm, is a high-quality optical component sourced from Edmund Optics. It is designed to provide excellent protection for optical systems while maintaining high transmission rates in the 8-12 µm spectral range.

The window features a Broadband Anti-Reflective (BBAR) coating on both the front and back surfaces, identified as 'edm arcedgermanium81'. This coating is specifically designed to reduce surface reflections, thereby enhancing the overall transmission of the window. The BBAR coating ensures that the window performs optimally across the entire 8-12 µm wavelength range, making it an ideal choice for infrared (IR) applications.

The window's geometry is defined by its circular base shape and thin lens shape. The 75 mm diameter provides a generous aperture, suitable for a wide range of optical systems. The 5 mm thickness offers a good balance between mechanical strength and optical performance.
