IOR-values added by Sven-Erik Andersen
Currently holds 117 different materials/IOR's. This update on December 13., 1994.
The list may have various IOR for the same substance, that is becouse I have
found different values in different sources, or it's for differnt wavelengths.
This update has cleared up the mess under chemicals, given them there poper
name, and put them under the right subgroup. The chemical formulae-name stands
in the comment for that chemical. There has been a substansial add-on to the
crystall-group (!), partly becouse most under chemicals are crystalls, but and
not the least, becouse Mikhail Elashkin <art### [at] aoi isrirmsksu> from the
Independent Group "Developing Games Software", Russia, Moscow have contributed
with a nice collection of crystall-Ior values. The names of these crystalls have
been transcribed to latin letters from russian, and the resulting names may not
have the correct english names, those that I didn't recognice I have left as is,
but if someone should happen to recognice any, and knows the correct english
comment.
A little comment on these crystalls. Where I have a range of values for a
substance, (#declare Beryll_Ior_1 = 1.585 // 1.568-1.602)
^^^^^^^^^^^
I took the middle value for that range (some crystalls have several
valueranges).
Comments, add-ons, corrections etc. (much appreciated) to
