Each of the four partnersis building a major newinstrument.

The Goodman Spectrograph is UNC’s$1.8M contribution.

We make our own volume phaseholographic gratings

Net throughput > 90%Let there be light

How do we control it remotely?

We build a graphicaluser interface (“GUI”).[Work done by under-graduate Adam Craine & Professor Cecil]

We connect to thespectrograph,wherever it is, viaInternet-2.
