WQK4040-AI1 40 x 40 mm N-BK7 Precision Rectangular Window; t=6mm AR 630-1100nm

Discover the WQK4040-AI1, a 40 x 40 mm N-BK7 Precision Rectangular Window with a thickness of 6mm, designed for applications that require high-quality optical components. This window is sourced from Knight Optical, a renowned vendor known for their extensive catalog of optical elements.

The WQK4040-AI1 is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties and high damage threshold. This Schott glass type is known for its low coefficient of thermal expansion, making it an ideal choice for applications involving temperature fluctuations.

The window features anti-reflection (AR) coatings on both the front and back surfaces, optimized for the wavelength range of 630-1100nm. This coating significantly reduces surface reflections, improving transmission and minimizing ghosting and flare. The AR coating is of the Kni AI1 type, ensuring high performance and durability.

The window's rectangular shape, with dimensions of 40 x 40 mm, provides a larger aperture than round windows, making it suitable for applications where more light gathering is required. The thin lens shape of the window ensures minimal optical aberrations, making it ideal for imaging applications.

According to the provided item data, this window is in stock and available for immediate purchase. For more information, you can refer to the vendor's website using the provided weblink.
