title: Reduplication of a penta prism angle using master angle prisms and a plano-interferometer.
abstract: The use of small master angle prisms optically contacted to a large prism offers a method for reduplicating reflecting angle surfaces of prisms by interferometric measurements. Optical working and testing procedures are described for making a typical prism-the penta prism was selected.
