BK7 Windows

BK7 is a borosilicate glass material with good transparency and refractive index, making it a quality choice for optical windows, substrate materials, or wafers. Its benefits include properties such as low dispersion, high optical uniformity, and low absorption. It is primarily used in the visible and near-infrared spectra for industrial, medical, and high-precision, low-power laser applications with AR coatings to enhance transmittance.
