Discontinued Hamamatsu TEC cooled PbS and PbSe detectors can now be replaced with detectors from trinamiX. With their equal or better performance trinamiX detectors provide the familiar pin configuration with additional robustness and customization possibilities.
When measuring gas concentrations, the detection limit of the detectors determine the resolution and thus accuracy. The lower the limit the higher the resolution. trinamiX new application note compares the achievable limits of state-of-the-art photodetector technologies: NDIR Thermopile, Pyroelectric and PbSe sensors.
Whenever IR detectors are exposed to UV rays, such as sunlight or high temperature flames, they are vulnerable to permanent damage. trinamiX TO detectors can now be equipped with germanium or silicon windows, cutting off those harmful rays. Also, an additional anti-reflection coating can significantly improve the transmission in relevant wavelengths.
Environments with fluctuating temperature can be challenging for IR detectors. trinamiX now offers a unique solution for thermoelectrically cooled PbS and PbSe detectors: The thermistors are placed directly next to the detecting element. Keeping the temperature down improves the performance of the detectors in key metrics.
trinamiX introduces a self-test feature for its PbS and PbSe infrared detectors. Infrared detectors are the crucial part in flame monitoring, spark detection or gas sensing devices. If they are not working properly, the whole system fails. A periodic self-monitoring check of the detectors ensures their functionality and adds reliability.
trinamiX patented thin film layer encapsulation allows up to 16 Single Pixels to be combined in a small space without the need for additional hermetically sealed packaging. These Multiple Single-Pixel detectors can be used to identify multiple materials or concentrations of multiple gases. Also, both PbS and PbSe sensors can be added to one Multiple Single-Pixel. This solution has proven to not only be smaller and lighter but also less expensive than a broadband spectrometer system.
You want to get a basic understanding of PbS and PbSe detectors and how you can work with them? You are curious to understand why lead sulfide (PbS) and lead selenide (PbSe) infrared detectors are especially attractive and how they compare to other detector families such as InGaAs photodiodes or thermopiles? Take a look at trinamiX new White Paper.
