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.

The Powell lens has an advantage over cylindrical lenses because later one produces a poorly illuminated line, limited by the non-uniform Gaussian laser beam. Huge spherical aberration redistribute light along the line, decreasing the light in the central area while increasing the light intensity at the lineâ??s end. The outcome is uniformly illuminated line used in all manner of machine vision applications.

The right angle prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads, because they are easier to mount, and deform much less than mirror in response to external mechanical stress. As long as acceptance angle limitations for TIR from the roof faces are not exceeded, the right angle prisms can serve as a retro reflector, turning beams back to the original direction.Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.
