Abstract

Photometric measurements must be related to standards of reference to have any absolute significance. This paper describes the historical background of photometric standards and the prime and secondary devices and their relation to primary lamps from the National Bureau of Standards. The instrumentation and techniques used to perform the transfer of standards are described as well as the need for and use of these photometry standards.
