I bought it from Infiray. With shipping and wire transfer fees I think I paid about $300USD. I am interested to see if this can be used in a product so I signed agreements with them, etc.
@DaneLaw ~ yeah, I know that most modules are used in devices that appear USB UVC class cameras. I'm interested in interfacing at a lower level to leverage work I've already done with my other devices whose primary goal is to make radiometric data available to people (as opposed to presenting as a traditional thermal imaging camera, of which there are plenty). I think you are right though, there will be a bit of a rabbit hole with this sensor... Lots of details to fathom. I'm actually looking at Flir's documentation with respect now, LOL.
