InfraTec Infrared, a specialist in infrared sensing and thermography solutions with more than 35 years of expertise, is highlighting a new advancement in pyroelectric detector technology with the introduction of the DSV-7341 detector from its PYRONEER series. The company is exhibiting at SPIE Photonics West 2026, Booth #4525 for its Sensor Division and Booth #338 for its Infrared Measurement Division.
Headquartered in Dresden, Germany, with a subsidiary in the United States, InfraTec operates through two divisions: a Sensor Division focused on customized pyroelectric infrared detectors, and an Infrared Measurement Division supplying high-performance infrared cameras and turnkey thermography systems for a wide range of applications.
Detectivity Meets Stability in Pyroelectric Detection
The new DSV-7341 pyroelectric detector addresses a long-standing challenge in high-performance infrared detection - balancing maximum detectivity with reliable thermal stability. InfraTec’s PYRONEER detector series is based on DLaTGS (deuterated L-alanine doped triglycine sulphate), a pyroelectrically sensitive material that achieves up to three times higher detectivity than lithium tantalate at modulation frequencies in the kilohertz range. This performance makes DLaTGS detectors a gold standard for Fourier transform infrared (FTIR) spectrometers. However, higher detectivity also increases sensitivity to temperature fluctuations. The DSV-7341 overcomes this limitation through an innovative thermal management approach.
Integrated Temperature Control for Reliable Measurements
The new detector combines an integrated thermoelectric cooler (TEC) with a negative temperature coefficient (NTC) thermistor, enabling precise monitoring and regulation of the detector chip temperature. This active temperature control compensates not only for environmental thermal variations, but also for changing radiation levels - such as transitions between background and sample measurements. By stabilizing the detector under real-world operating conditions, the DSV-7341 delivers consistent, reliable performance while preserving the high detectivity advantages of DLaTGS material.
