Measurements of the Index of Refraction of Glass at High Temperatures (Classic Reprint) - Couverture souple
Synopsis
This book reports the latest findings on the index of refraction of glass at high temperatures. Prior research has shown that at temperatures near 500°C, glass undergoes critical expansion at a greatly increased rate, accompanied by an increase in heat absorption. The author sought to determine the effect of these temperature-induced changes on the index of refraction. Nine different samples of glass were subjected to interferometry, a precise method of measuring the index of refraction and determining changes in response to varying conditions. Measurements were taken at temperatures ranging from 20 to 700° C. Results showed that the index of refraction increased until reaching the critical temperature, then decreased as the rapid expansion set in, only to increase once more when the glass began to soften. Unexpectedly, the measured index was consistently higher than that computed using the established index-density relationship, indicating an increase in the index attributable to the same factor responsible for the shift in the glass's absorption band toward longer wavelengths. The author proposes that this phenomenon may be related to the observed changes in thermal expansion. This book provides valuable insights into the behavior of glass at high temperatures, with implications for optical system design and other applications involving high-temperature glass components.
