83-350 25 mm Dia. Germanium Protective Flat Window; t=2 mm BBAR 3-12µm

The 83-350 is a 25 mm diameter Germanium Flat Window, with a thickness of 2 mm, designed for use in optical systems that operate within the 3-12 µm wavelength range. This window is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for immediate purchase.

The window is made from Germanium burnett, a material known for its excellent transmission properties in the infrared region of the spectrum. This makes it an ideal choice for applications that require high-quality, broadband infrared transmission. The window is coated with a Broadband Anti-Reflective (BBAR) coating, specifically the edm arcedgermanium31 coating, on both the front and back surfaces. This coating is designed to reduce surface reflections, thereby improving transmission and enhancing overall system performance.

The window's geometry is defined by a circular base shape with a diameter of 25 mm and a thickness of 2 mm. This thin lens shape ensures minimal optical distortion while providing sufficient mechanical strength for most applications. The window's flat design further minimizes optical aberrations, making it suitable for use in high-precision optical systems.
