31-391-000 3 in Dia. Zerodur Single Surface Flat Window; t=0.75 in Uncoated

The 31-391-000 is a 3-inch diameter Zerodur single surface flat window, uncoated, with a thickness of 0.75 inches. This product is sourced from the renowned optical components vendor, Edmund Optics.

The window is designed with a circular base shape, a common feature in optical components to ensure uniform light distribution. The diameter of this window is 76.19999999999999 inches, providing a substantial surface area for light transmission. The thickness of the window, 0.75 inches, is designed to minimize optical aberrations while maintaining structural integrity.

The material of this window is Zerodur, a special glass-ceramic material developed by Schott AG. Zerodur is known for its excellent thermal stability and low thermal expansion coefficient, making it an ideal choice for applications requiring high precision and stability over a wide temperature range.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. This can be beneficial in applications where the user wants to apply their own coating or where a coating is not necessary.

The window is designed for use at a wavelength of 587.6 nanometers, a common wavelength used in various optical applications. The window's shape is that of a thin lens, further enhancing its light transmission capabilities.
