Product description

H-K9L colorless optical glass windows

Product description:

(N-BK7)composition: SiO2=69.13% B2O3=10.75% BaO=3.07% Na2O=10.40% K2O=6.29% As2O3=0.36%.

(BK7) optical glass has excellent mechanical properties and very low air bubbles and impurities, good scratch resistance. Because of its chemical stability, no special treatment grinding and polishing. Used in optoelectronics, microwave technology, and many other areas of diffractive optical elements.
