Pyroelectric Detectors 

26 Mar 2020

LASER COMPONENTS is a world leading manufacturer of pyroelectric detectors. From our research and production facility in Arizona we supply customers all over the world with these robust thermal detectors.

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.

The devices are manufactured in standard transistor style packages and have long expected lifetimes making them ideal for fit and forget applications such as gas sensing, detecting intruders and identifying the presence of a flame. We can supply detectors with up to four channels allowing for the detection of three gases simultaneously.
