Aluminum for Reflectors

May 01, 1934

Some of the earlier methods used in meeting the demand for improved reflecting surfaces of aluminum reflectors are reviewed, and data are presented showing reflectivity for radiation of various wave-lengths. A new anodic treatment known as electrolytic brightening is described, and the results attained by the application of this process are discussed.
