    Basic Info

    H-K9 glasss or BK 7 glass is an optical borosilicate crown glass. it enjoys high transmission an virtually free of bubbles and inclusions. as used for lenses and prisms for lasers and optics, H-K9 glass has good physical properties and can be polished like leaded glass. it also weighs approximately 15% less than full (24%) leaded glass( crystal)..

    compostion:SiO2=69.13% B2O3=10.75% BaO=3.07% Na2O =10.40% K2O=6.29% As2O3=0.36%
    Since BK7 performs well in all chemical tests, no special handling is required, thus reducing manufacturing costs.
    H-K9(BK-7) glass provides excellent transmittance through-out the visible and near infrared spectra and down to 350 nm in the ultraviolet:
