H-K9L Wafers (BK7 Equivalent from CDGM)

H-K9L (a common BK7 equivalent) 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.

Following is a matrix of standard H-K9L wafer specifications which can be produced and shipped quickly – most often within Four weeks.  Our wafers are inspected and packed in a Class 100 Clean Room and certified to the listed specifications.  If you don’t find a product meeting your needs, please contact us and provide your required specifications.  Where appropriate, please use an existing Item Number and describe required exceptions.

Please note that there is a $300 and Ten Piece MINIMUM Order Quantity
