Note that fused quartz has a very different and lower refractive index compared to crystalline quartz which is birefringent with refractive indices n o = 1.5443 and n e = 1.5534 at the same wavelength. Although these forms have the same chemical formula, their differing structures result in different optical and other physical properties.
Standard refractive index measurements are taken at the "yellow ... Fused silica (a pure form of glass, also called fused quartz) 589.29: 1.458 [1] [14] Other ...
For common optical glasses, the refractive index calculated with the three-term Sellmeier equation deviates from the actual refractive index by less than 5×10 −6 over the wavelengths' range [5] of 365 nm to 2.3 μm, which is of the order of the homogeneity of a glass sample. [6]
Refractive index variation for SF11 flint glass, BK7 borosilicate crown glass, and fused quartz, and calculation for two Abbe numbers for SF11. The Abbe number, [ 1 ] V d , {\displaystyle V_{\mathsf {d}}\ ,} of a material is defined as
The absolute refractive index n of an optical medium is defined as the ratio of the speed of light ... Fused silica (quartz) 1.46 [11] PMMA (acrylic, plexiglas ...
Unless stated otherwise, the properties of fused silica (quartz glass) and germania glass are derived from the SciGlass glass database by forming the arithmetic mean of all the experimental values from different authors (in general more than 10 independent sources for quartz glass and T g of germanium oxide glass). The list is not exhaustive.

The rotation of the crystal planes can be right or left-handed, again producing opposite optical activities. On the other hand, amorphous forms of silica such as fused quartz, like a racemic mixture of chiral molecules, has no net optical activity since one or the other crystal structure does not dominate the substance's internal molecular ...
