Optical prOperties Of selected elements

J. H. Weaver and H. p. r. frederikse

These tables list the index of refraction n, the extinction coeffi-

cient k, and the normal incidence reflection R (φ = 0) as a function

of photon energy E, which is expressed in electron volts (eV). To

convert the energy in eV to the wavelength in µm, use λ = 1.2398/

E. To compute the dielectric function

from the complex

index of refraction

N = n + ik, use ε

The optical constants in these tables are abridged from three

more extensive tabulations:

• Optical Properties of Metals (OPM), Volumes I and II,

Physics Data, Nr. 18-1 and 18-2, J. H. Weaver, C. Krafka,

D. W. Lynch, and E. E. Koch, Fachinformationzentrum,

Karlsruhe, Germany.

• Handbook of Optical Constants (HOC), Vol. I, 1985, and

Vol. II, 1991. E. D. Palik, Ed., Academic Press, Inc., London.

• American Institute of Physics Handbook (AIPH), 3rd

Edition, D. E. Gray, Ed., McGraw-Hill, New York, 1972.

The first two of these major sources provide detailed compari-

sons of all optical data available in the literature at the time of the

compilation. For critical applications the reader should refer to the

original work. References for individual metals and semiconduc-

tors are listed at the end of the tables. Generally, tabulated values

for the optical properties are accurate to better than 10%. Data

in parentheses are extrapolated or interpolated values. For most

elements the spectral range covered is from the far infrared (0.010

or 0.10 eV) to the far ultraviolet (10, 30 or 300 eV). The intervals

between successive energies in the tables are chosen in such a way

that the major spectral features are preserved.

Very small values of k are expressed in exponential notation,

e.g., 1.23E-5 means 1.23 × 10

The following table is convenient for identifying the energy en-

tries in these tables with the corresponding wavelengths:

1 mm 0.00124

500 µm 0.00248

100 µm 0.01240

50 µm 0.02480

10 µm 0.12398

5 µm 0.24797

1000 Å 12.398

400 Å 30.996
