Name:
Named in 1980 by Pete J. Dunn, Donald R. Peacor, and Bozidar Darko Sturman in honor of Richard "Dick" Philip Hauck [June 30, 1935 Bloomfield, New Jersey, USA - ] formerly of Bloomfield, New Jersey, USA, and now a resident of Franklin, NJ. Author and co-founder of the Sterling Hill Mining Museum, Ogdensburg, NJ. He is a charter member and a former President of the Franklin-Ogdensburg Mineralogical Society, the Geoliterary Society, and the Franklin Mineral Museum. He is a lifelong, avid collector of minerals, books, and mining memorabilia, especially from Franklin, NJ. His library ranks among the most extensive private libraries in the world dedicated to mining and mineralogy. Pronounced HOW-KITE.

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. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized uniaxial interference figure - the conoscopic
(convergent-light, Bertrand-lens-in) view, for a grain cut with the optic axis
centred and vertical. The coloured rings are isochromatics, computed with the
same physics as the Michel-Lévy bar above; the dark cross is the isogyre.
For a genuinely uniaxial mineral viewed this way, that cross stays perfectly stationary if you rotate the stage - unlike a biaxial mineral, where it splits apart on rotation. That invariance is itself the standard diagnostic test for telling uniaxial and biaxial minerals apart at the microscope.
