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. WebThe difference to fused silica which is most commonly used for sensing experiments is the small refractive index of MgF2 which is very close to that of water. Compared to fused silica this leads to more than 50% longer evanescent fields and a 4.25 times larger sensitivity. Moreover the birefringence amplifies the sensitivity difference…

Absolute refractive indices and thermal coefficients of fused silica ...

WebSilica (SiO2) is an impurity that must be removed from a metal oxide or sulfide ore when the ore is being reduced to elemental metal. To do this, lime (CaO) is added. It reacts with the silica to form a slag of calcium silicate (CaSiO3), which can be separated and removed from the ore. (a) Write the balanced equation for this process. WebIn fused silica, the density (refractive index) increases when glass is rapidly cooled from a higher temperature ( Bruckner, 1970 ). Micro-Raman spectroscopy has confirmed an increase in the concentration of 3 and 4 member rings in the silica structure in the laser-exposed region, indicating a densification of the glass ( Chan et al., 2001).
