Webmineral. Because thin sections are always the same thickness (h=3000 nm), the birefringence for a mineral in a particular orientation should be the same in all thin sections. Retardation for a particular mineral will be greatest when the mineral is oriented so that the two rays have the maximum and minimum refractive indices for the mineral. WebIn this case, the mineral will also show birefringence for most orientations, unless one of the privileged directions in the crystal is lined up with the E-W polarizing direction of the incident light entering from below But this time, one of the privileged directions corresponds to the ω direction and the other to an ε' direction in the crystal.
