Web14 mei 1983 · Abstract. The temperature dependence of the refractive indices of high-purity fused silica and crystal quartz was measured in the 450-1600 nm wavelength range and at temperatures from room temperature to 400 degrees C. The average thermal coefficients of the refractive indices of those materials show opposite sign.
