    I need a cheap camera (budget ~750$) for a IR study (erbium emssion)
    from 1.2 to 1.6 microns. Looks like some older vidicons and some low
    cost russian Gen 1 tubes cover that range, any ideas? Of course a CCD
    would be wonderful, but telecom cameras start at around 2K, unless I'm
    wrong.

    Steve. You are looking for something that isn't very available. I've searched ongoing for years. The only solid state camera sensitive in the 1.2-1.6 range and the last price I had on those is over $15k USD. This is considered the SWIR range. Btw,
    the use of a filter on a ccd is useless. I have a vidicon camera with the extended IR range sensitive out to 2.2um. The other guy didn't say so but the last tube of this type I bought cost me $3000 and that was over 5 years ago. The silicon CCD has no
    sensitivity out that far in the IR. They are only good to about 1.1um at best and that is where the sensitivity goes well below 1%. I have one of these SWIR cameras and I also have one of the IR 2.2um vidicon cameras. I can rent these but it will be a
    little costly. EMAIL me at [email protected]. Bill

    I sort of doubt that Steve is still looking, 12 years later. ;)

    (Usenet has been around for a really long time.)

    The Electrophysics 7290A lead salt vidicon camera works fine out to 2.2
    um and is available on eBay periodically for $1k or less. It has a bit
    of an image persistence problem, but for slow-moving stuff it's great.

    Cheers
