I am looking for a company that makes multi-channel infrared detectors for the mid-IR (about 5 to 15 microns). I have encountered thermopile arrays that work in this wavelength region. One such detector has four independent channels. The thermopile area of each channel is covered by a narrowband IR filter so that the thermopile detects absorption from the wavelength of interest. Also interested in different type of IR detectors that cover the same region but should be cheap and operate at room temperature.
