WQK2502-AI2 25 mm Dia. N-BK7 Precision Round Window; t=4mm AR 1050-1700nm

The WQK2502-AI2 is a high-precision, circular window with a diameter of 25 mm and a thickness of 4 mm. This window is made from N-BK7, a popular glass type from Schott, known for its excellent optical properties and wide transparency range.

The window features an anti-reflection (AR) coating, specifically designed for the wavelength range of 1050-1700nm. This coating reduces reflection at the surface of the window, thereby improving transmission and minimizing signal loss. The coating is applied to both the front and back surfaces of the window, ensuring optimal performance from both sides.

The window is designed in a thin lens shape, which is ideal for applications where minimal thickness and weight are crucial. Despite its thin profile, the window maintains high mechanical strength and durability, making it suitable for various optical systems.

This window is available from Knight Optical, a reputable vendor known for its high-quality optical components.
