BK7® is a high quality optical glass used in lenses and other optical components where the additional benefits of Fused Silica are not required. It is a relatively hard material with extremely low bubble and inclusion content. H-K9L has a low refractive index (≈1.52), low dispersion, and provides excellent transmittance through-out the visible and near infrared spectra, down to 350 nm in the ultraviolet.
