47-687 25 mm Dia. Germanium Protective Flat Window; t=3 mm BBAR 8-12µm
This 47-687 optical window, sourced from Edmund Optics, is a 25 mm diameter, 3 mm thick germanium flat window, coated with BBAR (Broadband Anti-Reflection) coating for the 8-12 µm wavelength range. The window is designed to protect optical systems from environmental hazards while minimizing reflection losses.
The window's base shape is circular, making it suitable for a wide range of applications. The BBAR coating on both the front and back surfaces enhances transmission in the specified wavelength range, ensuring optimal performance. The window's thin lens shape further contributes to its functionality.
The window's vendor, Edmund Optics, provides a valid web link indicating the product's availability. This assures users of the window's readiness for immediate use in their optical systems. The window's germanium material, combined with its BBAR coating, makes it an excellent choice for mid-infrared applications.
