Detectors for use in analytical devices and in spectroscopy have been part of InfraTec's portfolio for over 20 years. From the very beginning, these are based on high-quality, single-crystal lithium tantalate (LiTaO3). Introducing DLaTGS as a pyroelectric material last year, InfraTec developed the new PYRONEER series from InfraTec, which also includes spectrometer detectors based on LiTaO3. These well-proven detectors with precious metal black layers have now been redesigned.
Tried-and-tested material in a future-proof design
The advantages of lithium tantalate are clearly evident. With its high Curie temperature of more than 600 °C, LiTaO3 offers rugged and reliable detector performance as well as excellent long-term stability of the signal voltage. Due to a very low temperature coefficient and a lower dependence of the measurement sensitivity on the incident power, the material is ideally suited for use in changing environmental conditions, as is typical for mobile spectrometers.
The LSV LiTaO3 detectors in the PYRONEER series are based on the proven LIE-312(f) and LIE-332(f) detectors. Their design has been adapted to the modern manufacturing technologies developed for DLaTGS detectors. Thus, the LiTaO3 spectrometer detectors can be reliably and efficiently manufactured in the desired quantities in the future as well.
The design update also included sustainability optimizations for the LiTaO3 detectors. The LSV series fully complies with the strict limits of the current RoHS Directive.
