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 famous for high birefringence and transparence in broad region of spectrum. It is ideal material for manufacturing polarizing prisms, beam divergent elements, laser gates and other optical devices, polarization components.
