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.

These detectors offer flat spectral response from UV to far Infrared with signal output also being linear from 10-6 to 0.1 W/cm2. Operating range is from -50°C to 100°C (-58 to 212°F) with short exposure up to 125°C (257°F) being possible. The company emphasizes the great versatility of the new detector. It can be furnished with one of many different filters and with a choice of argon, neon, nitrogen or xenon encapsulating gas.

Responsivity is typically 50.5 V/W. Minimum and maximum values are 40.7V/W and 60.3 V/W, respectively. Typical detectivity is 0.98 x 108 cm√HzW with 0.69 and 1.44 being minimum and maximum values respectively.

The new Micro detectors from Dexter Research Center offer exciting performance and packaging opportunities in non-contact temperature measurement applications, such as Tympanic ear thermometers for premies and newborns.

The ST60 has similar applications in gas analysis in hospitals and other medical facilities as well as automotive testing. Further it may find use in laser detection and in industrial and temperature sensing.
