Effective optical constants of anisotropic materials

Applied Optics, 1980
The applicability of a technique for determining the optical constants of soil or aerosol components on the basis of measurements of the reflectance or transmittance of inhomogeneous samples of component material is investigated. Optical constants for a sample of very pure quartzite were obtained by a specular reflection technique and line parameters ...

Optical constants in ion-irradiated graphite

Surface and Coatings Technology, 1994
Abstract The ion-beam-induced amorphization of crystalline graphite layers was studied by using near-IR visible and near-UV reflectance spectra to obtain the real and imaginary parts of the refractive index as a function of photon energy in the range 0.5–7 eV.

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 ...

Notes on Optical Constants

Mathematical Proceedings of the Cambridge Philosophical Society, 1925
The tensor calculus introduced in a recent paper proves a powerful method of investigating the light scattered laterally as exemplified in the blue of the sky. The late Lord Rayleigh worked out the effect on the polarisation of having non-spherical molecules, and the present note is practically a repetition of his work but with a somewhat greater ...

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.

Optical constants of cubic boron nitride

Physical Review B, 1989
The optical constants of cubic boron nitride were determined for the first time in the vacuum ultraviolet. The fundamental optical-absorption edge determined from these optical constants is 6.1\ifmmode\pm\else\textpm\fi{}0.2 eV.

Optical constants of carbon dioxide ice

Applied Optics, 1986
Laboratory measurements of the absorption coefficient and refractive index of solid CO2 are reviewed for all parts of the electromagnetic spectrum from the ultraviolet to the microwave with emphasis on values for temperatures above 77 K. The available measurements in some cases require reinterpretation.

Optical constant determination of thin films

Applied Optics, 1988
A method for the determination of the complex index of thin films is described based on the reflectance of the film in the presence and absence of a transparent overcoat film. It is shown that by proper choice of overcoat film, the real and imaginary components (n and k) of the index can be separated so that a simple graphical representation is ...
