Me earlier reply was incorrect.  FreeSnell evaluates optics along an
exponential curve between the two endpoint wavelengths.  It was done
this way so that changing the abscissa units does not affect the
ordinates displayed.  Also, having varying increments between
wavelengths prevents (sampling) aliasing from affecting the whole plot
uniformly.

 | Yes, using the samples keyword:
 | 
 |    (wavelengths 1e-6 10e-6)
 |    (samples 10)
 | 
 | would compute the optical properties at intervals of 1 um.
 | Or are you interested in non-uniform intervals?
