Abstract:

Six samples of ruby crystals grown by the Linde Company, Thermal Syndicate, Ltd., and Airtron have been subjected to several optical tests. The four types of tests performed are based on optic axis figure, shadowgraphs, examination between crossed polarizers, and small-angle scattering. The test results are presented primarily in photographic form. Optic axis figures were reasonably good in all but one of the samples examined. The shadowgraphs show striae in all of the samples and in some, wedges resulting from relatively uniform refractive-index gradients. One sample shows no small-angle scattering. In the other samples small-angle scattering is quite variable and strongly dependent on direction of transmission through the crystals. Examination between crossed polarizers provided no additional information. Author
