WebMax Birefringence: 0.009-0.015 Angstroms : Elongation: elongate parallel to c axis : Dispersion: r >v , weak : Distinguishing Features: Staurolite's yellow color, pleochroism, relief and habit make it distinguishing. It is vitreous and has a grey streak. Staurolite's hand sample has characteristic penetration twinning and unique crystal habit. WebThe efficacy of the new procedure is demonstrated for graphite. The optical constants that have been determined for linearly polarized synchrotron light incident with p - and s -geometry provide a detailed and reliable representation of the complex refractive index of the material near π- and σ-resonances.
WebThe alliance of two types of π-conjugated planar anions BO 33− and COOH − produced an optimized layered structure to maximize the anisotropic polarizability, resulting in an extremely large birefringence (0.156@546 … Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive indices exhibited by the material. Crystals with non-cubic crystal structures are o…
