Parameters
Type LIE, LIM: Detectors with standard design
LME, LMM: Detectors with reduced microphonic effect
LRE, LRM: Detectors with micromechanical frame
LFP: Detectors with tunable Fabry‐Pérot filter
Housing TO18, TO46: 5.4 mm in diameter
TO5, TO39: 9.2 mm in diameter
TO8: 15.2 mm in diameter
The number following the hyphen indicates the number of pins.
Channel Number of measuring channels
Aperture (mm) Size of the circular or rectangular aperture through which radiation hits the sensitive elements.
Operating modes Size of the circular or rectangular aperture through which radiation hits the sensitive elements.
JFET/OpAmp Integrated signal condition like integrated junction field effect transistors (JFET) for detectors in voltage mode or integrated operational amplifiers (OpAmp) for detectors in current mode.
Thermal Compensation A pyroelectric detector is sensitive to changes in temperature. Changes in ambient temperature have an influence on the measurement signal and shifts the operating point. This effect reduces a thermal compensation. Therefore, each pyroelectric element gets an additional optically inactive element, which compensates for unwanted currents.
Low Micro Patented micromechanical chip attachment (LowMicro) by InfraTec to reduce the effects of interfering impact sounds.
Detectivity* As a key parameter, the specific detectivity D* characterizes the signal-to-noise ratio of infrared detectors.

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

NDIR Spectroscopy
NDIR Spectroscopy

NDIR 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.

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.
