The "chemical Imaging Camera" mentioned in the article is based upon a real device. It's likely an infrared spectrometer using a focal plane array detector. It operates in the mid infrared (2500 nm to 13,800 nm) rather than the near infrared where most IR cameras operate (780 nm to 1500 nm). The mid-IR is a spectral region that contains the chemical signatures of covalently bonded materials. A detector like this costs between $100K and $200K, depending upon resolution, and that does not include the cost of the rest of the spectrometer. They are typically used on FT-IR microscopes, but I have heard one company working on a macro-imaging system. Most of the major FT-IR instrument vendors offer such a system (i.e. Thermo Nicolet, BioRad (bought recently by Varian), Perkin Elmer, Bruker). I would love to get one in my lab, but they are way to expensive and our single point detectors on our microscopes are sufficient for the work I do.
Here is a link to the products offered by Varian.
