Up for sale are two optical fiber cables. One cable has a core diameter of 200um and the other is 600um.  Both have standard SMA-905 connectors so they will fit all Ocean Optics products as well as other brand spectrometers with SMA-905 connectors.  Besides having great range from 180nm to well over 1100nm, they are the perfect length when you need to have everything close together.  Also, because the cables have a different diameter, it is a good way to see the effects of different diameter cables for under $100.  Thank you.

I have been an eBay member since 2001 with excellent positive feedback.  I am very familiar with these cables so if you have any questions please scroll up and click "contact seller". Thank you.
