Some examples and use cases from the internet:

• Circa 1890, the Viennese mineralogist F. Becke indicated that, when one defocused the thin section under the microscope, the direction of displacement of a luminous fringe in contact with two contiguous minerals is done according to the relative value of their refractive indexes.

• The following chart lists the refractive indices for 143 varieties of gemstones, arranged in descending order.
• layers of insulator materials in which the interference properties of a design composed of materials of various refractive indices are used to reflect, transmit or absorb various wavelength bands.
• This performance is optimal when the refractive indices of the sample and the intervening media match.
• 'Dielectric layers' are coatings constructed of multi
• Different refractive indices lead to spherical aberrations and geometrical distortions of the structures.
• The higher the numerical aperture of the objective and the deeper the structures of interest inside the sample, the more important it is to match the refractive indices of the sample and the immersion medium.
• Measuring the refractive index is one of the first steps in identifying a gemstone, though some gemstones have similar refractive indices and additional tests are required for a definitive identification.
• Choose objectives with a motorized correction collar to simplify adaption to different refractive indices.
