InfraTec Detector and Filter Over­view

The modular construction system of InfraTec’s pyroelectric detectors consists of approximately 50 standard types and therefore offers optimized solutions for a variety of applications in the field of sensor technology. Detectors with reduced microphone technology and integrated operational amplifier as well as digital detectors are part of our product range.

Parameters

Type

LIE, LIM: Detectors with standard design
LME, LMM: Detectors with reduced microphonic effect
LRE, LRM: Detectors with micromechanical frame
LRD, LID: Detector with digital Interface

Housing

TO18, TO46: 5.4 mm in diameter
TO5, TO39: 9.2 mm in diameter
TO8: 15.2 mm in diameter
Channel

Number of measuring channels

Aperture (mm)

Size of the circular or rectangular aperture through which radiation hits the sensitive elements.

Operating modes

Voltage Mode: The pyroelectric current is initially converted into a voltage by an RC network followed by a conversion to lower impedance.

Current Mode: The pyroelectric current is permanently compensated by an OpAmp. The current required for this generates a voltage drop across an RC network in the feedback path which serves as the measurement signal.

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.
