Pyroelectric Detectors
Differential Pyroelectric Detector
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.
One-Channel LiTaO3 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 LiTaO3 Pyroelectric Detectors
Multi-channel pyrodetectors: dual-channel, triple-channel and quad-channel versions are available.
Pyroelectric DLaTGS Detectors
DLaTGS detectors exhibit the most effective pyroelectric effect known. Their major application is FTIR.
DLaTGS = Deuterated Lanthanum α Alanine doped TriGlycine Sulphate
Choice of Filters for Pyroelectric Detectors
An IR filter makes all the difference. Thermal detectors are naturally polychromatic, and a filter is needed to detect specific gases/wavelengths.
