Dexter Research Center announces the availability of its ST60 Micro and ST60R Micro silicon-based thermopile detectors. The ST60R Micro measures .161″ (4.09 mm) in diameter and is believed to be the world’s smallest infrared thermopile detector. The ST60 detector is also available in TO-5 and TO-18 packages, as well as a special TO-5 package that features a diffractive lens with a narrow field of view. Arrays of up to four elements are also possible in the TO-5 package.
