Optical calcite crystal (iceland spar) both in raw material and semi-finished form or finished form (such as polarizers, waveplates, etc.) ready to be used as per customer's dimension or detail technical specified.
Typical products are rhombohedral shapes, rectangles and rounds, shaped plates, wedges, and cubes
It is carefully selected to eliminate small inclusions, cleavage planes, cloud and mist, point defects and bubbles inside the crystal.
It is known for its properties of transparency and double refraction, used chiefly in the manufacture of polarizing prisms, which are essential parts of polarization components and other special optical instruments.
