Pyroelectric Detectors

Advanced single channel voltage mode detectors for FTIR instruments.

Excellent linearity and fast response to IR flux change.

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.

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

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.
