This book details a novel method for measuring spectral transmission that the author has developed, using a photoelectric cell in combination with an electrometer in a null method. This method has a number of advantages over other existing methods: it eliminates errors due to the photoelectric current not being strictly proportional to the radiant power incident on the cell, eliminates errors due to dark current, and eliminates errors due to the use of the electrometer as a deflection instrument. The author describes the apparatus used in detail, including the spectrometer, the photoelectric cells, the electrometer, and the rotating sector. The author also provides instructions on how to use the apparatus and how to calculate the transmission of a specimen. This book will be of interest to anyone interested in the measurement of spectral transmission, including physicists, chemists, and engineers. 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.
