Database of Optical Constants for Cosmic Dust

Optical Constants at low Temperatures

The optical constants have been determined by Kramers-Kronig analysis from reflectance measurements at polished surfaces of bulk samples. Experimental details are given in Henning and Mutschke (1997), Posch et al. (2007) :

All n-k-Data tables consist of three columns. The first one contains the wavelength in micron. The second one is the real part of the complex refractive index (n), the third one is the imaginary part (k).

For the details of the derivation of all n-k-Data we refer to the mentioned publications (see the List of Publications).
