Pyroelectric Detectors

Pyroelectric crystals generate positive and negative charge carriers simultaneously on opposing sides.

The LD21XX and DD31XX series are exclusive pyroelectric detectors in which both crystal sides are amplified separately.

Single Channel Current Mode Pyroelectric Detector

Single channel pyroelectric detectors made of LiTaO₃ are available for current mode (CM). They are used for gas detection and flame detection.

Multi-channel pyrodetectors: dual-channel, triple-channel and quad-channel versions are available.

DLaTGS detectors exhibit the most effective pyroelectric effect known. Their major application is FTIR.

DLaTGS = Deuterated Lanthanum α Alanine doped TriGlycine Sulphate

An IR filter makes all the difference. Thermal detectors are naturally polychromatic, and a filter is needed to detect specific gases/wavelengths.
