Temperature dependence of refractive index of SiO2 glass
TLDR
In this paper, the authors measured the refractive index of silica glass in the UV and visible regions from −165.4 to 83.3°C and fitted the wavelength dispersion at each temperature by the three-term Sellmeier equation.Abstract:
The refractive index of silica glass has been measured in the UV and visible regions from −165.4 to 83.3°C. The wavelength dispersion at each temperature was fitted by the three-term Sellmeier equation. Analysis of the Sellmeier equation shows that the temperature dependence of the refractive index originates from the temperature shift of the observed shift of the exciton peak at around 10.4 eV.read more

Sellmeier coefficients and dispersion of thermo-optic coefficients for some optical glasses.
TL;DR: The Refractive index and its variation with temperature, the thermo-optic coefficient (d n/dT), are analyzed with two separate physically meaningful models for more than a dozen of some important Schott and Ohara optical glasses to find the refractive index at any operating temperature for any wavelength throughout the transmission region.

Temperature-dependent Absolute Refractive Index Measurements of Synthetic Fused Silica
TL;DR: Using the Cryogenic, High-Accuracy Refraction Measuring System (CHARMS) at NASA's Goddard Space Flight Center, this article measured the absolute refractive index of five specimens taken from a very large boule of Corning 7980 fused silica from temperatures ranging from 30 to 310 K at wavelengths from 0.4 to 2.6 microns with an absolute uncertainty of plus or minus 1 x 10 (exp -5).

Optical transitions in crystalline and fused quartz
TL;DR: RefReflectance data for crystalline and fused quartz are presented and analyzed for the energy range to 26 eV. The curves are very similar for each form of SiO2 suggesting the importance of localized effects in determining these optical properties as mentioned in this paper.
