WebThe refractive index of any substance is best described as a complex number, such as 1.34 + i 0.00067. The real part of this number is the ordinary refractive index as discussed above, whilst the imaginary part indicates the amount of absorption. If the imaginary part is zero, the substance is non-absorbing.

In general, an index of refraction is a complex number with both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength—thus, the imaginary part is sometimes called the extinction coefficient.
