Product Announcement

New MEMS Based Thermopile ST60

13 Dec 2017

LASER COMPONENTS has been working with Dexter Research Centre, a world

leading manufacturer of thermopile detectors, and we are pleased to announce the

launch of a new MEMS based thermopile that can withstand operating temperatures

of 300 degrees centigrade. Thermopile detectors are passive radiation sensing

devices that require no bias or cooling and generate an output in the range of micro

to millivolts.

 

The ST60 has an active area of 0.61 x 0.61mm2 and can be fitted with a low cost

polysilicon resistor which is used as a positive temperature coefficient thermistor. To

operate at these elevated temperatures requires careful choice of the materials used to

construct the detector, one example of this is the Diamond Like Carbon coated silicon

window.

 

The voltage produced is proportional to the temperature gradient between junctions

and, unlike pyroelectric detectors, thermopiles are very low noise devices generating

no 1/f or microphonic noise. Also, thermopile detectors provide a stable output for

DC radiation up to a frequency limited by the time constant of the detector.

 

Applications include non-contact temperature measurements such as tympanic

thermometers, automobile climate control and occupancy sensing, process

temperature monitoring, household appliances, and radiometers, gas analysis in

medical, automotive, and petroleum industries, hazard control including flame and

explosion detection, horizon sensors for scientific and space, and applications.
