Pyroelectric detectors with long lifetimes

The company can supply detectors with up to four channels allowing for the detection of three gases simultaneously. 

A pyroelectric infrared detector consists of a pyroelectric crystal sandwiched between two electrodes; these devices are thermal sensors that respond to a change in the IR radiation absorbed on the crystal surface.

A pyroelectric crystal is distinguished by having an atomic structure that will move slightly in response to a change in temperature, rearranging the electric charge within the solid generating a voltage across the electrodes. Pyroelectric detectors are characterised by much higher responsivity than other thermal detectors.
