  Penta Prisms






    The Penta Prism can deviate an incident beam without inverting or reversing to
    90 degree. The deviation angle of 90 degree is independent of any rotation of the
    prism about axis parallel to the line of intersection of the two reflecting faces.
    It is commonly used in Plumb Level, Surveying, Alignment, Range Finding and
    Optical Tooling. The reflecting surfaces of the prism must be caoted with a
    metallic or dielectric coating. The standard Penta Prism reflecting surfaces are
    coated with aluminum or enhanced aluminum.
