Excerpt from Optical Radiation Measurements: The Nbs 20-60-and 85-Degree Specular Gloss Scales
General Equations will be derived for the gloss and luminous flux ratio using an uh polarized light source according to the definition. If the light source is not completely unpolarized, separate measurements should be made with the light source polarized parallel and perpendicular to the plane of incidence. A calibration equation for the luminous flux ratio is derived to permit converting the measured quantities with polarized components to gloss for an unpolarized light source.

Paperback. Zustand: New. Print on Demand. This book will guide the reader through the methods used to measure the appearance of surfaces based on the long-standing research and technological developments at the National Institute of Standards and Technology. The methods involve determining how different surfaces interact with polarized light at varying angles. The author explains how these methods were adapted and calibrated to establish the standardized scales used by organizations like the American Society for Testing and Materials. The text also provides readers with detailed instructions on how to use spectrometric equipment and provides clear descriptions of the mathematical equations and derivations that justify these measurement techniques. With this book by their side, readers will be able to make accurate measurements of optical radiation and gain a deeper understanding of the fascinating field of specular gloss.
