Our pyroelectric infrared detectors and arrays based on lithium tantalate are designed for the use in non-contact temperature measurement and also in gas analysis, spectroscopy and security applications.
The wide range of available sensor designs enables us to provide customised solutions for small and large quantities.
By using modern ion beam etching technology very good noise to signal ratio values are achieved.
Our lithium tantalate pyroelectric single and multi-element infrared detectors are developed for use in gas analysis, spectroscopy, pyrometry and security applications.
Many types of infrared sensors manufactured in volume production are available. Beyond customized infrared sensors solutions are possible.
The pyroelectric linear array comprises a lithium tantalate chip with 128, 256 or 510 elements. The signals produced by the elements are processed in a CMOS circuit. Signal processing is carried out by the analogue circuitry, which comprises a multiplexer, an output amplifier and an adapted low-noise preamplifier for each pixel. The pyroelectric chip and CMOS readout circuit are located on a thick film substrate, which is mounted inside a hermetic metal housing. The incident radiation passes through a window which is transparent to infrared wavelengths, and reaches the sensitive elements.
