Fused Silica, Silica, Silicon Dioxide, Thermal Oxide, ThermalOxide의 굴절률
“Fused quartz” and “fused silica” are medium refractive-index glasses containing predominately SiO2 in the amorphous (non-crystalline) form. The word quartz usually refers to the natural crystal or mineral as opposed to the phrase “fused quartz” which refers to the glass that is created out of a manufacturing process which involves heating quartz crystals to temperatures of around 2000 degrees Celsius (which has lower refractive index).
Fused quartz has better ultraviolet transmission than most other common glasses (such as borosilicate glasses that have somewhat higher refractive indices), making it an ideal candidate for applications in the sub-400nm spectral region. Additionally fused quartz/fused silica have a low thermal expansion coefficient and are resistant to scratches, water, and acids. Normal varieties of fused quartz contain water which gives it strong absorption bands in the infrared, though there are water-free varieties commercially available. Its 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.
