Infrared Flame Sensor

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.

Infrared Spectroscopy

Infrared Spec­tro­scopy

Infrared Spec­tro­scopy

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.

All branches and application areas

Detector Search

InfraTec offers different product groups including approximately 50 standard pyroelectric detectors. Detectors with reduced microphone technology and integrated operational amplifier as well as digital detectors and high-performance detectors for spectrometers are part of our product range.
