CaCO3 Birefringent Crystals
Description
Calcium carbonate crystal (formula for CaCO3) is a kind of uniaxial crystal, which is the most pure crystal in the carbonate rocks. Its birefringence is large, range of spread spectrum is wide, and show a certain size of the diamond shape,it has the largest polarized light and polarized light performance,it is suitable for the visible and near infrared polarization material and the grand ideal material used in the glen Taylor, glen Thompson and glen laser polarizing film.
