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.
