Pyroelectric detectors are thermal detectors; i.e. they create an electric signal due to temperature changes in the chip. This temperature change is caused by absorption of light. We do use LiTaO3 and DLaTGS as pyroelectric materials. Basically such detectors cover the whole spectra. However, they are mainly used for mid-wave and long-wave infrared detection (MWIR and LWIR). In addition, the usage in the THz region seems to become more popular these days.
Our Differential Pyroelectric detectors use our new dual ended amplification scheme, giving double the output. Currently available in single channel CM versions.
Pyroelectric LiTaO3 single channel detectors available for current mode, CM, and voltage mode, VM. Used for gas detection or flame detection.
In this section one will find pyroelectric LiTaO3 detectors with dual, triple or quad channels. Mostly used for gas analysis.
Deuterated Lanthanum α Alanine doped Triglycine Sulphate (DLATGS) detectors have the most effective pyroelectric effect known. Their major application is FTIR.
