WQK4001-AI1 40 mm Dia. N-BK7 Precision Round Window; t=6mm AR 630-1100nm

The WQK4001-AI1 is a high-precision, 40 mm diameter round window made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This window, sourced from Knight Optical, boasts a thickness of 6 mm and is coated with an anti-reflective (AR) coating suitable for wavelengths between 630 and 1100 nm.

The window's N-BK7 material, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for various optical applications. The window's flat design, or Sub Type "Flat Window", ensures minimal distortion and maintains the integrity of the light path.

The window's geometry, defined by its 40 mm diameter and 6 mm thickness, provides a robust and stable platform for optical systems. The thin lens shape further enhances its usability in various applications.

The window's anti-reflective coating, applied to both the front and back surfaces, reduces reflection and increases transmission, thereby enhancing the overall efficiency of the optical system. This coating is specifically designed for the wavelength range of 630 to 1100 nm, making it suitable for near-infrared (NIR) applications.
