Innovation for PYRONEER^®: High performance detector with thermal stabilizing

Precise temperature control is key to maximizing infrared detector performance and minimizing signal drift. InfraTec addresses this in its PYRONEER^® DLaTGS detectors by integrating a thermoelectric cooler (TEC) and a negative temperature coefficient (NTC) thermistor. Together, these components enable continuous monitoring and active stabilization of the detector’s internal temperature.

This stabilization compensates for both environmental fluctuations and changes in incident radiation, such as differences between background and sample measurements. The result is improved measurement accuracy, reproducibility, and long-term stability.

Steady Feedback for Reliable Temperature Regulation

The NTC thermistor, placed close to the detector chip, provides a resistance signal corresponding to the internal temperature. This signal is used by an external TEC controller to adjust the current and regulate heating or cooling as needed. In combination with modern design and manufacturing, this ensures efficient and stable thermal operation.

Key Benefits at a Glance

• Active temperature stabilization via integrated TEC and NTC
• Reduced signal drift and higher measurement precision
• Compensation for environmental and radiation-induced changes
• Reliable feedback loop for precise control
• High thermal efficiency and system stability

TEC increases independence from environmental conditions, making PYRONEER^® detectors suitable for both mobile and high-end FTIR spectrometers. Improved packaging of the DSV-7341 also enables a simple, reproducible connection to a heat sink for efficient thermal management.
