Uh... true!  My mistake, I actually had in mind the difference between air and
vacuum which is  near 0 and so I assumed vacuum's ior was 0, sorry!  Also for
the crown glass at 1.54 ( i actually thought it was about 2.2...)...  But I
learned this 2 years ago in a general physic course...

Thanks for the tips!
