The Spectrometer I used is an Ocean Optics HR2000. It's a small box about 2" x 4" x 6" and has a FO input and a USB connection. It is powered from my laptop via the USB port.
I bought mine at an MIT Flea Market last summer. The SW is available from the manufacturer. I don't recall what I paid, but it was certainly less than $250. If anybody is interested in one, I still have the seller's contact information. He may still have them. I believe these particular units came from a biomedical analyzer of some sort. The gratings (hence the dispersion) can be changed at the factory, but it costs something like $500 last seen. Best, -John ============== > > > >> J.
