Hi all,
Last weekend Colin Winter held an online chat on spectroscopy,
especially on the OPL spectroscopes.
It was a great talk with one of the legends in the gemmological
field. You can find the chatlog at http://yey.be/Winter.cgi and the
tools at http://oplspectra.com.
Next month Vincent Pardieu, director of the AIGS lab in Bangkok will
do us the honours.
