Our company can supply optical Calcite Crystal (Iceland Spar) both in raw and semi-finished form or as finished polarizers ready to be used with custom dimensions or as 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.
