THE ABSOLUTE SPECTRAL REFLECTIVITY OF CERTAIN PIGMENTS AND METALS IN THE WAVELENGTH RANGE BETWEEN 2 AND 15 MICRONS

摘要

Data on absolute spectral reflectivity as a function of wave- lengths between the spectral region of 2 and 15 microns are presented;the collection of these data was made possible through the use of "Black Body" Reflectameter (designed by the members of the staff of this project) used In conjunction the Perkin-Elmer infrared recording spectrometer. The results reveal important points of consideration for one who is engaged in choosing materials for infrared work;some of these points are discussed.
