Measurement of Optical Constants: Optical Constants of Liquid Mercury at 5461 Å*
Journal of the Optical Society of America, 1966The 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 polyacetylene
Synthetic Metals, 1985Abstract Optical constants of neat cis - and trans -(CH) x and (CD) x films are determined by measuring infrared, visible and ultraviolet spectra of the film and its thickness directly. The absorption coefficient of cis -(CH) x at the absorption maximum 18 500 cm −1 was (1.5 ± 0.1) × 10 5 cm −1 and that of trans -(CH) x at 15 500 ...

The high-frequency optical constants of graphite are computed from electron energy loss results by using a dispersion relation for anisotropic materials. The values of ɛ⊥(ω) are in reasonable agreement with those obtained by Taft and Philipp from optical measurements.

The most apparent properties of metals, their luster and their color, have been known to mankind since metals were known. Because of these properties, metals were already used in ancient times for mirrors and jewelry. The color was utilized 4000 years ago by the ancient Chinese as a guide to determine the composition of the melt of copper alloys: the ...

The complex dielectric functions, ε(E)=ε 1(E)+ iε 2(E), of ZnO have been measured by spectroscopic ellipsometry (SE) in the photon-energy range between 1.5 and 5.0 eV at room temperature. The SE measurements are carried out on the surface parallel to the optic axis c, which allows the determination of ...

Physical Review, 1961
The optical constants for electrolytically polished silver samples were determined from normal-incidence reflectance data in the spectral region 2 to 10 ev. The sharp minimum in the curve for $k$ near 3.8 ev, which is associated with the onset of interband transitions, is deeper than in previous results. A second minimum is observed near 9.2 ev.

The refractive index and extinction coefficient of purple K3Sb film prepared on a quartz substrate were determined from the transmittance data in the photon-energy region 0.5–6.2 eV through the Kramers–Kronig (KK) dispersion analysis. The interference effect due to the internal reflection of the light in the substrate was eliminated by taking the ...

Optical Constants of Aluminium
Proceedings of the Physical Society, 1960The optical constants of aluminium from the near ultra-violet (2500A) to the near infra-red (5μ) can be described, at least qualitatively, in terms of the Drude formula by the two parameters N and τ, the density of free electrons and the relaxation time, respectively.

Optical Constants of be Mirrors
Optical Interference Coatings, 1988Very little information is available concerning the optical constants of polished bare beryllium mirrors especially for beryllium produced by hot-isostatic pressing (HIP) and vacuum hot-pressing (VHP) material manufacturing techniques. The optical constants would be useful in thin-film coating designs for Be mirrors.
