The WW11050 is a wedge window with a 1-inch (25.4 mm) diameter, 5 mm thickness, and a wedge angle of 0.008726646259971648 radians, sourced from Thorlabs. This window is made of N-BK7, a type of borosilicate glass manufactured by Schott, which is known for its excellent optical properties and durability.
The wedge shape of this window is designed to minimize surface reflections and improve optical transmission. The wedge angle is small enough to limit the effects of beam deviation while still providing the benefits of reduced reflections. The window is uncoated, meaning it does not have any additional anti-reflective or protective coatings.
This window is suitable for use in a wide range of optical systems and applications, including beam delivery, laser machining, interferometry, and more. It is available for purchase directly from Thorlabs, and the provided weblink indicates that it is currently in stock.
