Pyroelectric Detectors

Advanced single channel voltage mode detectors for FTIR instruments.

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

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

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

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

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