48-117-000 3 in Dia. Zerodur Single Surface Flat Window; t=0.75 in Uncoated

The 48-117-000 is a 3-inch diameter Zerodur single surface flat window, with a thickness of 0.75 inches, offered by Edmund Optics. This window is designed for use in various optical systems, providing a clear aperture for light transmission.

The window is made of Zerodur, a low-expansion glass-ceramic material developed by Schott AG. Zerodur is known for its excellent thermal stability and dimensional accuracy, making it an ideal choice for precision optical applications. It has a lambda/20 surface flatness, ensuring high-quality imaging and minimal optical aberrations.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where the natural properties of the Zerodur material are desired, or where additional coatings may interfere with the system's performance.

The window's geometry is circular, with a diameter of 76.2 mm, and a thickness of 19.05 mm. This thickness provides rigidity to the window while maintaining a low weight, making it suitable for various applications.
