WQK4040 40 x 40 mm N-BK7 Precision Rectangular Window; t=6mm Uncoated

The WQK4040 is a high-precision rectangular window, measuring 40 x 40 mm with a thickness of 6mm, manufactured from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This window is sourced from Knight Optical, a reputable vendor known for their quality optical components.

The window is designed in a flat configuration, ideal for applications that require minimal optical distortion. Its rectangular shape, a common choice in many optical systems, provides versatility in design and application. The window's thickness, 6mm, offers a good balance between structural integrity and light transmission, making it suitable for a wide range of applications.

The N-BK7 glass, or Schott BK7, is a borosilicate crown glass known for its low dispersion and high homogeneity. It has a refractive index of 1.5168 at 633nm, making it an excellent choice for visible light applications. The window is uncoated, meaning it does not have any additional layers to alter its optical properties. This can be beneficial in applications where the natural properties of the glass are desired.
