    Price Drop: JDSU 10mW single-line argon, $195 + shipping

    Hi all, I have a JDSU 10mW single-line argon for sale. I bought the PSU and head separately, so they aren't a matched set, but they work fine together. The head is rated at 10mW, however it will put out just over 30mW at max current, measured with my Ophir LPM (not that you would want to...
