011-0209E 25.4 mm Dia. N-BK7 Plano-Convex Window; t=6mm Uncoated

The 011-0209E is a Plano-Convex Window, a type of curved window, with a base shape of a circle and a diameter of 25.4 mm. This window has a center thickness of 6 mm and an effective focal length (EFL) of 967.15 mm, making it suitable for a variety of optical applications. The curvature of the window is defined by a radius (r1) of 500 mm.

This window is made from N-BK7, a type of glass manufactured by Schott, which is a leading international technology group in the areas of specialty glass and glass-ceramics. N-BK7 is a borosilicate glass known for its excellent optical properties, making it a popular choice for various optical components.

The window is designed to operate at a wavelength of 588 nm. It has a spherical shape, which is a common choice for optical components due to its ease of manufacturing and excellent optical properties. The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties.

This window is available from EKSMA Optics, a vendor known for its extensive catalog of optical components. According to the vendor's website, the window is in stock, indicating that it is readily available for purchase and delivery.
