89-563 25 mm Dia. Germanium Protective Flat Window; t=1 mm BBAR 3-5µm

The 89-563 is a 25 mm diameter Germanium Flat Window, with a thickness of 1 mm, designed for protective purposes. This component is sourced from Edmund Optics and is currently in stock, as indicated by its weblink status.

The window is made of Germanium burnett, a material known for its excellent transmission properties in the infrared region of the spectrum. It is specifically designed to transmit light between 2 and 14 µm, making it ideal for applications such as thermal imaging, night vision, and other infrared-based technologies.

The window features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces. This coating, identified as 'edm arcedgermanium35', is designed to reduce reflection and increase transmission across a broad spectrum of wavelengths. The coating is specifically tuned to provide optimal performance between 3 and 5 µm, further enhancing the window's suitability for infrared applications.

The window's geometry is defined by its 25 mm diameter and 1 mm thickness. This thin, lightweight design makes it ideal for use in systems where weight and space are at a premium. Despite its thin profile, the window is robust and durable, providing excellent protection for the optical components it is designed to safeguard.
