Paperback. Condición: New. Print on Demand. This book from the National Bureau of Standards considers the history of standards and measurements, providing recommendations for more accurate photometric measurement processes. The author outlines the background of radiometry, photometry, and spectrophotometry, explaining how these fields are used in the measurement of optical radiation. They cover the engineering applications for this type of measurement and evaluation, then investigate the various inaccuracies which may occur due to the translucent blurring effect, or flux loss, when applied to translucent materials like plastics or glass. They offer solutions to minimize or correct for these errors and go on to explain how their methods and findings can be applied to colorimetry and other areas of optical sciences and engineering. Overall, this book is a significant contribution to the science of optical radiation measurement, providing valuable insights and practical solutions for researchers and practitioners alike.

Paperback. Condición: New. Print on Demand. This book introduces the Transmittance Measurement Assurance Program (MAP) service. It also provides documentation for the service through a comprehensive list of references and presents the results of a pilot run for the MAP service given in a sample calibration report. This book provides a means for a laboratory to assess the accuracy of its spectral transmittance measurement capabilities. A laboratory which participates in this program will be sent a package of transmittance filters which have been measured at NBS. These are to be measured by the laboratory on its spectrophotometer(s) and returned, together with the measurement results, to NBS. NBS will then remeasure the filters and send a final analysis of the result to the participating laboratory. The range of filter measurements provided in the MAP package permits an evaluation of the accuracy of a laboratory's spectral transmission measurements and will often reveal the cause of systematic errors if any exist. This publication describes the contents and use of this MAP package. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
