He Rui Optics BK7 windows has a low refractive index (approximately 1.52) and low dispersion, offering excellent transmission in the visible and near-infrared spectral ranges, and can even transmit ultraviolet light at 350 nanometers. Due to its good physical and chemical properties, K9 glass is widely used for protective windows in laser applications, general optical applications, optical elements such as lenses and prisms, mirror substrates, and substrates for optical coatings.
