Abstract
A modification of the Drude method for the measurement of the optical constants of metals is described, in which the eye is replaced by a photoelectric cell and the extinction position is determined objectively by means of a Lindemann electrometer. By the use of a compensating device, the inaccuracy normally resulting from unsteadiness of the light source is avoided. The results of measurements on copper, nickel, chromium, palladium, and zinc are quoted.Keywords
