Webbirefringence, i.e., optical retardation per unit of thickness (typically, nm/cm). In addition, an accurate observation of color shifts requires a precise orientation of the sample between the polarizers. This technique is generally subjective, and relies heavily on the trained observation skills of the individual operator. It also relies on the WebAn advanced class of retardation plates enables the operator to introduce variable amounts of phase shift in order to offset specimen birefringence. These devices, as discussed above, are termed compensators and are …
