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.
