47-686 12.5 mm Dia. Germanium Protective Flat Window; t=2 mm BBAR 8-12µm

This 47-686 optical window, sourced from Edmund Optics, is a 12.5 mm diameter, 2 mm thick germanium flat window, designed to protect optical systems from environmental hazards. The window features a Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces, optimized for the 8-12 µm wavelength range. This coating enhances transmission while minimizing reflection, ensuring optimal performance in the mid-infrared (MIR) region.

The window's thin lens shape and circular base contribute to its wide range of applications, making it suitable for use in various optical systems. The germanium material, known for its excellent transmission properties in the MIR region, further expands its usability. The window's geometry, with a diameter of 12.5 mm and a thickness of 2 mm, ensures durability while maintaining a low profile, making it an ideal choice for applications where space is a constraint.

The window is currently in stock and available for immediate purchase through the provided weblink. With its robust design, superior coating, and optimal wavelength range, this germanium flat window is an excellent choice for users seeking high-performance optical protection in the MIR region.
