Introduction:
BK7 Glass is a borosilicate crown optical glass with high homogeneity, low bubble and inclusion content. Its good physical and chemical properties make BK7 Glass widely used in visible and near IR range. Most of windows, lenses and prisms, which used in laser, optical system, optical communication, are made from BK7 Glass.
