This item is an interactive Java simulation depicting the Michel-Levy birefringence color chart.  By clicking on the virtual chart, students can observe how birefringence, thickness of specimen, and path difference are correlated.

This is an interactive Java simulation designed to serve as a model for understanding the behavior of light as it passes through anisotropic crystals.

This is an interactive Java simulation that depicts a virtual calcite crystal superimposed over the word "Birefringence".  By rotating the crystal and axis of the polarizer, users can see the image doubling effect caused by the crystal's birefringent properties.

This is an interactive Java simulation on the topic of birefringence.  It explores how the orientation of a crystal's optical axis is related to divergence of orthogonal wave pathways through the crystal.

This is an interactive Java simulation by the same authors on the topic of birefringence.  It simulates light being passed through a crystal of calcite (Iceland Spar), which has strong birefringent properties.  The user will see a double image from the refracted light rays.

This is an interactive Java simulation that depicts a 3-D ellipsoid that represents an optically positive birefringent crystal.  Users can adjust the optic axis and refractive index to observe the dielectric properties in all directions.
