Telecom-Grade White Float Window: 50mm Diameter, 4mm Thick, AR 1050-1700nm

This is the WGT5004-AI2 50 mm Dia. B270 Glass Round Window, a high-quality optical component designed for telecom applications. Sourced from Knight Optical, this window boasts a catalog number of WGT5004-AI2 and is currently in stock, as indicated by its weblink status.

The window is a flat, circular design with a diameter of 50mm and a thickness of 4mm. It is made from B270 Schott glass, a popular choice for its excellent optical properties and durability. The window is coated with Kni AI2 on both the front and back surfaces, providing anti-reflective properties in the 1050-1700nm wavelength range.

The Kni AI2 coating is a broadband anti-reflection coating designed for high-power laser applications. It reduces surface reflections to less than 0.5% at normal incidence, improving transmission and reducing unwanted back reflections. This makes the window ideal for use in high-power laser systems, beam delivery systems, and other telecom applications.

The window is shaped as a thin lens, which is beneficial for applications where weight and thickness are critical factors. Despite its thin profile, the window maintains excellent optical performance and durability, making it a versatile choice for various applications.
