InfraTec Detector Talks 09/2025 - NDIR Sensors and Detectors

Online Event: Detector Talks 2025 – Basics and Benefits for NDIR-Applications

Read press release

In medical examination of respiratory air, detection of leaks in gas pipes or process monitoring in production: NDIR gas analysis is used for a wide range of tasks. As part of the “Detector Talks 2025 – Basics and Benefits for NDIR Applications”, InfraTec’s specialists will present various applications in more detail.

The Rugged Ones – PYRONEER Detectors with Lithium Tantalate

Open press release

Detectors for use in analytical devices and in spectroscopy have been part of InfraTec's portfolio for over 20 years. From the very beginning, these are based on high-quality, single-crystal lithium tantalate (LiTaO3). Introducing DLaTGS as a pyroelectric material last year, InfraTec developed the new PYRONEER series, which also includes spectrometer detectors based on LiTaO3. These well-proven detectors with precious metal black layers have now been redesigned.

PYRONEER Series becomes Moisture Resistant

More about the PYRONEER detectors for particularly harsh environments

InfraTec takes detector stability and reliability to the next level with its high-performance PYRONEER family. For particularly harsh environments, there is now an alternative to the KBr window: soldered zinc selenide (ZnSe) featuring an antireflection coating (ARC).

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 are part of our product range.
