Optical Constants of Germanium

Applied Optics, 1967
The authors have attempted to assess the disagreement of various investigators on the optical properties of germanium in the far uv. The analyis subjected the reported data, out to about 25 eV, to the following tests: (1) an internal consistency check when possible by applying the Kronig-Kramers dispersion relations to the optical constants; (2) an ...

Optical constants of minerals and rocks

Applied Optics, 1975
Lorentz line parameters (and estimates of their standard deviations) have been empirically derived from measured reflectance data for muscovite mica, an anorthosite, a diopsidic pyroxenite, an almandite-pyrope garnet, and a soda lime glass. These parameters provide a useful starting point for computer calculations requiring optical constants as a ...

Intrinsic optical constants of aluminum

Applied Optics, 1987
Des resultats experimentaux obtenus dans trois laboratoires differents ont donne, apres des corrections dues a la couche d'oxyde, des constantes optiques identiques dans le domaine spectral 350-650 ...

Elasto-optical constants of Si

Physical Review B, 1993
The three independent components of the piezo-optical tensor P ijkl (ω) have been determined in uniaxially stressed Si using rotating-analyzer ellipsometry. This tensor, with only three complex independent components in the case of Si, links the changes in the real and imaginary parts of the dielectric tensor Δe ij (ω) to an arbitrary stress X=X ki [i.

Optical constants of sodium sulphide

Physica Status Solidi (a), 1979
Infrared and Raman measurements are reported. From these, real and imaginary parts of the dielectric constant, longitudinal and transverse optical mode, the static dielectric constant and the effective charge are calculated.

Complex Optical Constants on a Subwavelength Scale

Physical Review Letters, 2000
Optical phase contrast has for the first time been observed on a nanometer scale, with a near-field microscope of scattering type that maps the complete optical field of amplitude and phase. Backed by quasielectrostatic theory, we demonstrate the significance and experimental accessibility of even complex optical constants on a subwavelength scale ...

Optical Constants of Metals

Physical Review, 1960
A calculation of the interband contribution to the frequency dependent dielectric constant of metals is attempted based on a specific model. The frequency region near the threshold for the interband transitions is considered. Emphasis in the model is laid on the bending of the energy bands near the Brillouin zone boundary. Attention is focused on cases

Measurement of Optical Constants: Optical Constants of Liquid Mercury at 5461 Å*

Journal of the Optical Society of America, 1966
The optical constants of liquid mercury have been measured by ellipsometry at a wavelength of 5461 A. The measured results are n = 1.485 and κ = 3.061. Discrepancies among values from the literature are discussed and the magnitude of the important sources of error are evaluated.
