the twin ordinary ray readings remain stationary while the other two move as the stone is rotated." Such additional shadow edges, ranging from two to four pairs (four to eight lines in total), also have been referred to as satellite readings (Schiffmann, 1972, 1975).
Glan-Taylor and Glan-Laser calcite polarizing beam-splitters separate S-polarized light (extraordinary rays) from P-polarized light (ordinary rays) over wavelengths from 400 to 1700 nm, which makes them an excellent choice for visible and near-IR applications.
