CCD Camera's, any good for viewing 1320nm?

I want to buy a 1320nm 15W laser to experiment with (with appropriate eye protection, of course), has anyone tried to view the beam at this wavelength using a CCD camera or is that a bit too far out of their sensitivity?

Re: CCD Camera's, any good for viewing 1320nm?

I've never played with that particular wavelength, but I do know normal cameras don't pick up 1500nm.
There are MWIR cameras, but they are only made by one company, and are very expensive, and there
is no guarantee that a laser won't mess them up. Don't even think about trying a FLIR. I've heard lasers
and FLIR don't mix well.

The only answer is an IR phosphor card. Thorlabs is about the only place anymore.

It won't pick it up. Silicon becomes transparent around 1200nm. You might need something like an InGaAs detector array.
