These materials can change the refraction coefficient very fast.

The figure 0.87 is obtained from 1 minus the refraction coefficient (~0.13).

The field exerts a refraction effect (much like a prism),” says Bourdieu, and its “refraction coefficient” measures “its degree of autonomy” (Bourdieu 1992).

It's refraction coefficient of light is the same as water, therefore FANTOM line is virtually invisible in water.

In general, the thickness of the lens changes little, while the lens refraction coefficient is based on differences in chemical composition and different.

In certain example embodiments, the multilayer AR coating includes a plurality of pairs of alternating high refractive index and low refractive index layers.

The optical glass of the present invention has optical constants of a refractive index (nd) within a range from 1.74 to 1.80 and an Abbe number (ν d) within a range from 47 to 51, contains, as essential components, SiO2, B2O3.
