89-560 12.5 mm Dia. Germanium Protective Flat Window; t=2 mm BBAR 3-5µm

The 89-560 is a 12.5 mm diameter Germanium Flat Window, with a thickness of 2 mm, designed and manufactured by Edmund Optics. This protective window boasts a Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces, optimized for a wavelength of 4000 nm.

The window is made of Germanium burnett, a material known for its excellent transmission properties in the infrared spectrum. The BBAR coating further enhances the window's performance by reducing reflection and increasing transmission, making it ideal for applications that require high-quality, high-transmission optical components.

The window's flat geometry ensures excellent optical quality, minimizing distortions and aberrations. The thin lens shape of the window allows for easy integration into various optical systems. The window is currently in stock and available for immediate purchase through the Edmund Optics website.
