The PYROMID® Detectors from InfraTec
The miniaturized multi-channel detectors of our PYROMID® detector series impress with their compact, highly integrated design. Some of these detectors also have integrated reflection beam splitters consisting of highly reflective, gold-plated microstructures. The complex design and manufacturing requirements for these detectors meant that, until now, only integrated amplification in voltage mode was possible in the TO39 design. With the LIM-082, users of gas measurement technology can work with a beam splitter detector with an integrated operational amplifier in a TO39 housing in current mode for the first time.
The LIM-082 – A Product of Highest Manufacturing Competence
Some PYROMID® detectors with a stacked design in a TO8 housing already come with an integrated operational amplifier. As an innovation leader for infrared detectors, InfraTec now combines two technologies in a miniaturized design for the first time: beam splitter and operational amplifier in a TO39 housing. The LIM-082 with its integrated operational amplifier provides a large, low-impedance output signal, which is why it is insensitive to interference coupling. This makes the LIM-082 suitable for direct connection to an A/D converter of a microcontroller. Even smallest gas concentrations can be measured precisely with fast response. The compressed design of the LIM-082 allows integration into the smallest end devices for gas analysis – for example for portable applications.
Special Features of a Beam Splitter Detector
Beam splitter detectors have an internal arrangement of micro mirror surfaces that act as internal beam splitters. When the incoming radiation hits these highly reflective gold-coated microstructures, it is split into several radiation beams of equal intensity but different directions. These beams then hit a pyroelectric sensor element with an upstream optical filter.
The beam splitter principle offers the benefits that mechanical expansions in the optical system of the measuring device, ageing effects or possible contamination in the optical path influence all measuring channels in the same way.
