47-688 50 mm Dia. Germanium Protective Flat Window; t=3 mm BBAR 8-12µm
The 47-688 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 window is 10600 µm, specifically designed for use in the infrared spectrum.
The window features Broadband Anti-Reflection (BBAR) coatings on both the front and back surfaces. These coatings, identified as 'edm arcedgermanium81', are designed to reduce reflection and increase transmission, enhancing the performance of the optical system.
The window is shaped as a thin lens, which is a type of lens where the thickness is much less than the diameter. This shape is often used in optical systems where a flat surface is required, such as in beam splitters or as a protective window.
