The IAA COsmic DUst LABoratory, a lab next door (building).

MAIN GOALS of this talk:

1. Let you know/remind you  that the IAA has a worldwide reference light 
scattering laboratory for experimentally studying the angular dependence 
of the scattering matrices of dust samples of astrophysical interest.

2. Convince the audience of:

- Polarization is highly valuable tool for retrieving information on the 
physical properties of small cosmic dust particles.
- How useful laboratory measurements can be for (among some other 
things) properly interpreting  astronomical observations .
