62-646 50 mm Dia. Germanium Protective Flat Window; t=3 mm BBAR 3-12µm

The 62-646 is a 50 mm diameter Germanium Flat Window, with a thickness of 3 mm, designed for use in optical systems. 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. The wavelength of this particular window is 10600 µm, making it suitable for applications that require the transmission of infrared light.

The window features a Broadband Anti-Reflective (BBAR) coating on both the front and back surfaces. This coating, identified as 'edm arcedgermanium31', is designed to reduce reflection and increase transmission across the 3-12 µm wavelength range. This makes the window ideal for use in applications where high transmission and low reflection are critical, such as infrared spectroscopy, thermal imaging, and other infrared-based technologies.

The window is shaped as a Thin Lens, which is a type of optical element that focuses light without introducing significant aberrations. This shape, combined with the window's high transmission and low reflection properties, makes it a versatile and valuable component in a wide range of optical systems.
