This is an interactive Java simulation that examines the use of compensators, often composed of quartz, muscovite or gypsum, which are used in the laboratory to produce a fixed optical path difference.

This item is an interactive Java simulation by the same authors on birefringence, also also known as double refraction.

This item is an interactive Java simulation depicting the effects of polarizer rotation on birefringent materials as seen in a virtual polarized light microscope.

This is an interactive Java simulation on the phenomenon known as birefringence, or double refraction.  It depicts a virtual microscope in which the user can rotate a crystal through a full 360-degree rotation to observe the effect.

This item is an interactive Java simulation by the same authors on the phenomenon known as Brewster's Angle, when the angle of incident light  reflected on an insulating surface is at maximum polarization.

This is a tutorial on light polarization appropriate for physics majors and students of introductory optics.

This item is an introductory tutorial on the basics of light polarization by the same authors, appropriate for non-science majors.
