89-571 75 mm Dia. Germanium Protective Flat Window; t=5 mm BBAR 3-5µm
The 89-571 is a 75 mm diameter Germanium Flat Window, featuring a thickness of 5 mm and a Broadband Anti-Reflection (BBAR) coating of 3-5 µm on both the front and back surfaces. This optical component is sourced from Edmund Optics, a reputable vendor known for its high-quality optical elements.
The window is designed with a circular base shape, making it suitable for a wide range of applications. Its geometry, defined by a 75 mm diameter and 5 mm thickness, ensures robustness and durability. The BBAR coating on both surfaces enhances transmission and reduces reflection, making it an ideal choice for applications that require high transmission and minimal reflection over a broad spectrum.
The material ID for this window is germanium burnett, a common material in optical applications due to its excellent transmission properties in the infrared region of the spectrum. This makes the 89-571 particularly suitable for applications in the infrared spectrum.
The window is currently in stock, as indicated by its weblink status. For more information, users can refer to the provided weblink, which leads to the product page on the Edmund Optics website.
