The Spectroradiometer — A new measuring instrument

摘要

The Spectroradiometer is an instrument recently developed at the Lancaster plant of the RCA tube department of the Radio Corporation of America. It is used to measure such optical properties of luminescent materials as color, visual efficiency, peak energy, build-up and decay of fluorescence and phosphorescence under continuous and discontinuous excitation, flicker, stability, photoconductivity, and infrared quench and stimulation effects.
