Calcite Crystal Description
Calcite crystal has the largest birefringence function and the largest polarization performance, and it is a natural crystal that cannot be artificially manufactured and cannot be replaced among known substances. Polarizing prisms and polarizers commonly used in the optical industry are the heart materials in the manufacture of astronomical sunspots and micrometers, as well as prisms in gem dichroic mirrors.
