WQK5000-AV2 50 mm Dia. N-BK7 Precision Round Window; t=6mm AR 450-900nm

The WQK5000-AV2 is a high-precision, flat window offered by Knight Optical, a renowned vendor of optical components. This window features a base shape of a circle with a generous diameter of 50 mm, making it suitable for a wide range of applications. The window's thickness is 6 mm, providing a good balance between durability and light transmission.

The window is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is often used in applications that require high precision and low dispersion, such as laser systems and imaging applications.

The WQK5000-AV2 is coated with Knight Optical's AV2 coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the visible spectrum, specifically between 450 and 900 nm. The AV2 coating ensures high-transmission performance, making this window an ideal choice for applications that require maximum light transmission.

The window is shaped as a thin lens, which can be beneficial in applications where a flat window is required but a lens-like effect is desirable. This could be the case in certain imaging or beam shaping applications.
