63-215 40 mm Dia. Germanium Protective Flat Window; t=4 mm BBAR 8-12µm

The 63-215 is a 40 mm diameter Germanium Flat Window, boasting a thickness of 4 mm and equipped with Broadband Anti-Reflective (BBAR) coating for the 8-12 µm wavelength range. This window is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.

As a Flat Window, this component is designed to protect optical systems from environmental hazards while minimizing optical losses. Its thin lens shape and circular base further enhance its functionality and compatibility with various optical setups. The window's germanium material, specifically the germanium burnett variant, ensures high durability and resistance to thermal shock, making it suitable for high-performance applications.

The BBAR coating on both the front and back surfaces of the window significantly reduces reflection, thereby enhancing transmission in the specified 8-12 µm wavelength range. This coating is particularly beneficial in applications such as infrared (IR) spectroscopy, thermal imaging, and other mid-IR optical systems.
