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.
Specific Detectivity* As a key parameter, the specific detectivity D* characterizes the signal-to-noise ratio of infrared detectors.
