Index of refraction uv fused silica
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… WebIn addition, UV fused silica has better homogeneity and a lower coefficient of thermal expansion than N-BK7. The low <0.25% reflectance per surface at 1064 nm makes …

WebAt low pulse energies just above the modification threshold (~ 100 nJ for 0.6-NA focusing of 800-nm, 100-fs pulses), a smooth refractive index modification has been observed in fused silica (Itoh et al., 2006), which is attributed to densification from rapid quenching of the melted glass in the focal volume (Chan et al., 2001 ). WebIts refractive index varies from 1.55 to 1.40 (for its transparent range: 160nm to 3000nm). Because fused silica is optically stable and consistent, many use it as a reference or standard for spectroscopic measurements. The details of its refractive index temperature dependence are also well studied.
The extremely low coefficient of thermal expansion, about 5.5×10 /K (20–320 °C), accounts for its remarkable ability to undergo large, rapid temperature changes without cracking (see thermal shock). Fused quartz is prone to phosphorescence and "solarisation" (purplish discoloration) under intense UV illumination, as is often seen in flashtubes. "U…
