Refractive Indices and Double Refraction Values
| Gemstone | Refractive Index | Double Refraction |
|---|---|---|
| Ruby (corundum) | 1.762-1.778 | 0.008 |
| Sapphire (corundum) | 1.762-1.778 | 0.008 |
| Benitoite | 1.757-1.804 | 0.047 |

What is a good refractive index?
Most plastics have refractive indices in the range from 1.3 to 1.7, but some high-refractive-index polymers can have values as high as 1.76. For infrared light refractive indices can be considerably higher. Germanium is transparent in the wavelength region from 2 to 14 µm and has a refractive index of about 4.
Does light travel faster in ruby or diamond?
v is the speed of light in the medium, n is the index of refraction. n > 1 because the velocity of light in the medium will never be faster or going the same speed as if it were traveling in a vacuum….Index of Refraction of Ruby and Sapphire.
| Mercury | 1.62 |
|---|---|
| Ruby | 1.76 |
| Diamond | 2.42 |
What does the refractive index of Ruby mean?
The “refractive angle” is the altered angle of the light as it passes through the stone’s interior. The Refractive Index is the ratio of difference between these two angles. Each material has its own unique density and Refractive Index. Refraction of light in Ruby.
How is the refractive index of a polymer measured?
Understanding Refractive Index The refractive index (RI) of a polymer is the ratio of the speed of light in a vacuum to the speed of light through the polymer. It varies with frequency (and thus wavelength) of light. Typically, it is measured at well-defined spectral wavelengths; for example, the yellow sodium double emission at 589nm wavelength.
What are the optical properties of a Rubie?
Optical Properties of Rubies : Refractive Index. Refractive Index. In optics, the refractive index or index of refraction of a substance or medium is a measure of the speed of light in that medium. As light moves from a medium, such as air, water, or glass, into another it may change its propagation direction.
What kind of plastic has a low refractive index?
“Usual” low refractive index plastics are specialty fluorinated polymers possibly bearing chemical function such as: Several polymer producers and some adhesive or coating manufacturers commercialize raw and compounded fluorinated polymers aiming optical applications.
