title: Versatile polarization interferometer.
abstract: A new form of polarizing interferometer has been assembled from six calcite-glass prisms and two halfwave plates. The interferometer has the large shear and long beam path capabilities needed for the examination of large objects and is capable of providing a stable interference pattern even when the two ends of the interferometer are supported independently. Lenses can be conveniently added to the system either to facilitate alignment or to extend its useful length.
