PYRONEER – High-Performance Detectors

InfraTec's PYRONEER detectors based on lithium tantalate (LiTaO3) or deuterated L-alanine doped triglycine sulphate (DLaTGS) have been developed for use in analytical instruments and spectroscopy. The precious metal black layer applied to the pyroelectric element guarantees homogenous absorption behavior in a wide spectral range.

    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.

    Operating Mode
    close

    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.

    Amplifier
    close

    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.

    LiTaO3-Detectors (Type LIE)

    Pyroelectric detectors for analytical devices have been part of the InfraTec portfolio for over 20 years. to the InfraTec portfolio. The first detectors in this series were based exclusively on high-quality, single-crystalline lithium tantalate (LiTaO3). This material offers a robust and reliable detector performance with a very low temperature coefficient and excellent long-term stability. With a precious metal black layer on the pyroelectric elements specially adapted for these detectors, they meet the highest requirements that are common in FTIR spectroscopy.

    DLaTGS-Detectors (Type DSV)

    The DLaTGS detectors are a real performance boost for FTIR spectroscopy. Based on the high-performance, pyroelectrically sensitive material DLaTGS (deuterated L-alanine doped triglycine sulphate), these detectors are clearly superior to LiTaO3 detectors with a triple detectivity (D*) at modulation frequencies in the kHz range. This combination of high pyroelectric coefficient, low heat capacity and low relative permittivity meets all requirements for achieving very good signal-to-noise ratios at very high modulation frequencies.

    In Fourier transform infrared spectrometers (FTIR) they are considered the gold standard among infrared detectors.

    For a Clear View

    When selecting the entrance windows for the detectors, a wide range of materials is available that are characterized by consistently high transmission over a wide wavelength range. Up to now, they have been available with an optional anti-reflective coating:

    • Barium fluoride

    • Potassium bromide

    • Caesium iodite

    • Zinc selenid

    In the future, InfraTec will also offer window materials that possess good transmission properties in the far infrared (FIR) and terahertz range. In particular, CVD diamond and polyethylene should be highlighted here.
