The refractive index gradient distribution of glass beads is the following formula. n(r)=√(2(r/a)²) In the formula, n (r) indicates the refractive index of the distance of the center point of the microsphere at the center point of r, and the a indicates the diameter of the microsphere.

Choosing a Refractive Index The accuracy of your laser diffraction particle size measurement depends by varying degrees upon the accuracy of your choice of refractive index. How to identify good refractive index from bad is one of the most common questions (and most common headaches) of the typical laser diffraction user.

The surface plasmon resonance angle mainly depends on the properties of the metal film, the wavelength of the incident light and the refractive index of the media on either side of the metal film . Because the refractive index is sensitive to temperature, it is important to perform the measurements at defined temperatures.
