Infrared Sensor Technology

We Manufacture your Infrared Detectors

At the company’s headquarters in Dresden we develop and manufacture pyroelectric infrared detectors in a large variety and of highest quality. They are used by our customers for high-precision gas analysis as well as for fire and flame detection. Local dedicated subsidiaries support our clients in the United States and in the United Kingdom.

Pyroelectric Detectors in Gas Analysis

Gas Analysis

The range of applications of pyroelectric detectors for gas analysis is very extensive, ranging from environmental measurements to the detection of gas leaks, steel analysis and medical patient monitoring while under anesthesia.

Infrared Flame Sensor

Use InfraTec’s fail-safe and consistently stable pyroelectric detectors for detecting typical spectral radiation, which is caused by burning organic substances.



In spectroscopes, very special pyroelectric detectors by InfraTec are used. Essential for this application are the uniform absorption characteristics over a wide wavelength range. This is made possible by a special absorption layer on the pyroelectric chip.

Detector Search

InfraTec offers five different product groups including approximately 50 standard pyroelectric detectors. Choose your suitable infrared detectors with the help of our detailed detector search.
