Optical Data of AfghaniteHide

Type:

Uniaxial (+)

RI values:

n_ω = 1.523 n_ε = 1.529

Max. Birefringence:

δ = 0.006
Based on recorded range of RI values above.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.

Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.

Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.

Thickness: 30 µm

Rotation:

Surface Relief:

Moderate
