Abstract: An electroformed cornercube retroreflector, wherein a conductive mandrel locates within an electrolyte containing metallic solution and through charging of the mandrel located within the solution attains electrodepositing of the metallic solution on to the mandrel for the purpose of plating a thick coating of the metal upon the mandrel. When the coating has achieved sufficient structural integrity to form a cornercube retroreflector, it is removed from the electrolyte, the deposited metal is separated or stripped from the mandrel to provide a natural highly inner polished metallic cornercube that can be placed within a partial sphere or other supportive body for use as a retroreflector for application for laser tracking in industrial or other applications.

Abstract: An instrument for measuring the throwing power, electrochemical efficiency and operating current density of an electrolyte comprises a number of removable electrodes (20) arranged inside a nonconductive probe body (10) with an open end (11) and an optional solution circulation opening at its opposite end (30) with the electrodes connected via current meters (80) to a current controller (70).
