Description Adds a wavelength-index point to a Sampled Material.
Syntax AddSampledMaterialWavelength id, wavelength, real, imag
Parameters id As Long Identifier of the sampled material.
wavelength As Double The wavelength of the sample point, in microns.
real As Double The refractive index at the given wavelength.
imag As Double The imaginary part of the refractive index at the given wavelength (may be zero).
Remarks This subroutine adds a wavelength-index point to a Sampled Material. If there is a problem the subroutine sets an error and returns without modifying the Sampled Material.
The imaginary component of the refractive index k is directly proportional to the absorption (or gain) coefficient at the associated wavelength via the following formula: a = ( 4p k / l) where a is the absorption coefficient, l is the wavelength and k is the imaginary part of the refractive index at that wavelength. Absorption is specified with a positive value, no absorption is specified with a value of zero, and gain may be specified with a negative value.
