Abstract

The present research on the optical properties of single magnesium crystals was carried forward in the laboratories of the University of Iowa under the direction of Prof. L. P. Sieg. Employing the crystelliptometer, plane polarized monochromatic light was reflected from the crystal surface and the resultant elliptically polarized light analyzed to determine the phase and azimuth angles of its components. The crystals were studied in two positions: parallel and perpendicular, respectively, to the principle axis of the crystal, and two sets of optical constants (index of refraction, absorption index and reflecting power) were determined. Within the range of wave lengths studied (4160- 6500A), the indices of refraction were: First position, 0.25 to 0.36; second position, 0.30 to 0.44. The reflecting powers ranged from 63% to 80%, and the absorption indices from 3.6 to 7.
