What material has highest refractive index?
diamond, has the highest refractive index among the following. 2) Relative refractive index , where the ratio is taken between the speed of light in two mediums other than vacuum.
What is the index of refraction for plastic?
1.3 to 1.6
Most plastics have a refractive index in the range of 1.3 to 1.6.
Which is clearer acrylic or glass?
Acrylic admits up to 92% of light, making it optically clearer than standard plate glass. In fact, clear acrylic can be made up to 33cm thick and still remain completely clear!
What kind of plastic is plexiglass?
Acrylic
Acrylic is a transparent thermoplastic homopolymer known more commonly by the trade name “plexiglass.” The material is similar to polycarbonate in that it is suitable for use as an impact resistant alternative to glass (particularly when the high impact strength of PC is not required).
What is the refractive index of nylon?
1.525

What is refractive index of germanium?
Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. For a typical sample of Ge the refractive index and extinction coefficient at 632.8 nm are 5.47661 and 0.7842102.
What is the refractive index of acrylic perspex?
For a typical sample of Acrylic the refractive index and extinction coefficient at 632.8 nm are 1.48899 and 0.
How is the optical performance of acrylic improved?
Its optical performance can be enhanced by applying scratch-resistant, SiO2-based, thin films. Sometimes these are referred to as “hardcoats”. While acrylic’s refractive index is usually close to the values reported below, this can be adjusted by copolymerization with other monomers. Fluoroacrylate monomers can lower the index.
What is the extinction coefficient of an acrylic sample?
For a typical sample of Acrylic the refractive index and extinction coefficient at 632.8 nm are 1.48899 and 0. Below are files of complete refractive index and extinction coefficients.
