More

H-K9L is a very hard material with an extremely low bubble and inclusion content. Additionally, H-K9L has a low refractive index (≈1.52), low dispersion, and provides excellent transmittance through-out the visible and near infrared spectra, all the way down to 350 nm in the ultraviolet.

H-K9L has fantastic physical and chemical properties which make it widely used in visible and near IR range. Windows, lenses and prisms, used in laser, optical system, optical communications devices, are made from H-K9L / N-BK7 glass.

Our CDGM H-K9L (BK7®) Glass Wafers are produced to all SEMI Standards including dimensional, flat and notch specifications. Additionally, wafers are inspected and packed in a Class 100 Clean Room and certified to the listed specifications.
