64-379 40 mm Dia. Germanium Protective Flat Window; t=4 mm BBAR 3-12µm
The 64-379 is a 40 mm diameter Germanium Flat Window, with a thickness of 4 mm, designed for protective purposes. This window is sourced from the reputable vendor, Edmund Optics, and is available for immediate purchase, as indicated by its "in stock" status on the company's website.
The window is made of Germanium burnett, a material known for its excellent optical properties. It is coated with BBAR (Broadband Anti-Reflection) coating, specifically the edm arcedgermanium31, on both the front and back surfaces. This coating enhances the window's performance by reducing reflection and increasing transmission across the 3-12 µm wavelength range.
The window's geometry is defined by its 40 mm diameter and 4 mm thickness, making it suitable for various applications. Its thin lens shape further expands its potential uses. The window's flat design ensures minimal distortion, making it an ideal choice for applications requiring high-quality, undistorted optical transmission.
