Paperback. Condition: New. Print on Demand. This book presents a fascinating and complex study of the use of an autocollimator telescope and auxiliary mirrors (ACTAM) in the world of reflectance measurements. A precise method for quantifying the reflectance of a surface, the Strong method involves reflecting light off a surface twice, calculating the absolute reflectance value as the square root of the ratio of the resulting signals. The author presents a novel approach to this method, using ACTAM to minimize uncertainty in the angular position of the sample, thereby improving measurement accuracy. The author discusses the instrumentation, adjustment, and measurement procedures, as well as the results and uncertainties associated with this technique. By exploring the intricacies of this method, this book provides valuable insights into the field of reflectance measurements and its applications in various scientific disciplines.

Paperback. Condition: 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.

Paperback. Condition: New. Print on Demand. This book presents a thorough examination of the Standard Reference Materials (SRMs) developed by the National Bureau of Standards (NBS) for calibrating the wavelength scale of optical spectrophotometers. These SRMs, primarily didymium glass filters with distinct absorption bands, serve as reliable and accurate references for wavelength calibration, covering a range from 400 to 750 nm. The author meticulously describes the certification process and provides data on wavelengths of minimum transmittance and inflection points, which are crucial for establishing wavelength scale corrections. The book also explores the various sources of uncertainty associated with the use of these SRMs and provides practical guidance on making use of the calibration data. By delving into the meticulous work behind the development of these SRMs, this book offers a valuable resource for anyone seeking to understand and utilize wavelength calibration standards in spectrophotometry.
