WQK4000 40 mm Dia. N-BK7 Precision Round Window; t=6mm Uncoated

The WQK4000 is a precision round window, boasting a 40 mm diameter and a thickness of 6 mm. Manufactured from N-BK7, a high-quality borosilicate glass, this window is sourced from Knight Optical, a reputable vendor known for their extensive optical component catalog.

This window is classified as a flat window, which means it does not have any curvature, making it ideal for applications where a flat surface is required. Its base shape is circular, making it suitable for applications where a circular aperture is necessary.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where the natural properties of the glass are desired, or where cost considerations are a factor.

The window is designed to be used at a wavelength of 633 nm, making it suitable for a wide range of applications in the visible light spectrum. Its geometry is that of a thin lens, which means it has very little optical power and can be used in applications where minimal distortion is required.
