- Brief description
- Anisotropic quartz rotated through 180°between crossed polarisers. the intensity of light transmitted through the analyser varies as a function of the angle of rotation of the quartz sample in the plane of the filters. At certain orientations, no light is transmitted. These 'extinction positions' are found at 90° intervals. From TLP Atomic Scale Structure of Materials
