A pyroelectric detector is an optoelectronic device with infrared sensitivity that is used specifically to detect electromagnetic radiation with wavelengths between 2 and 14 m.
A receiver chip for a pyroelectric infrared detector is made of single-crystalline lithium tantalate and is produced by InfraTec’s sensor business. Lithium tantalate ensures an extraordinarily low temperature coefficient with outstanding long-term stability of the signal voltage due to its extremely high curie temperature of 620 °C.
Due to their unique single polar axis, pyroelectric crystals exhibit a very uncommon asymmetry. Because of this, their polarization varies with temperature. In sensor technology, this so-called pyroelectric effect is exploited. For this, electrodes are coated perpendicular to the polar axis on a thin pyroelectric crystal.
A coating that absorbs light is put on the crystal’s upper electrode (the layer is black). The pyroelectric layer warms up and surface charge develops when this layer interacts with infrared radiation. When the radiation is turned off, an opposite-polarity charge starts to form. However, the fee is really minimal.
The Global Pyroelectric Detectors market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In EMEA, Optex introduces new indoor Flip X detectors. Optex’s innovative Flip X line of bendable indoor sensors. The new series has an innovative lens that can be turned to enable both narrow and wide detection in a single sensor, as well as a custom pyroelectric sensor for improved performance that conforms to the human shape.
Flexibility was taken into consideration when creating this “flipped” lens. Installers are basically given two sensors in one, allowing them to meet various consumer expectations. According to Optex, it can assist installers in managing their inventory and cash flow and give them the flexibility and assurance to show up on site with the appropriate solution to meet their customers’ demands.
Optex has a long history of offering superior sensing performance for applications involving intruder detection, and this new indoor sensor family is built on that foundation. The sensor can be used to cover either a large, open space, such as a living room or retail store, up to 12m at 85, or a long, tight area, such as a corridor up to 18m, by simply turning the lens through 180°.
Development of sensor technologies through research To meet both the demands of their own detector production as well as those of their customers, ongoing research and development of novel sensor technologies is essential. Their creators have extensive knowledge in the design of electro-optical and electro-mechanical systems, pyroelectric materials, and electronic signal processing.
This information serves as the foundation for creating novel items, optimizing production technologies already in use, and expanding their broad measurement methodologies. With PyrIQ, go digital. The analogue detectors are supplemented by the pyroelectric detector, which goes digital.
InfraTec created the digital pyroelectric detector PyrIQ to save costs for customers and make it easier to integrate a detector into a system. The detector parameters can be configured with great flexibility, allowing for flexible signal processing. It also converts the analogue signal with a 16-Bit resolution straight into a digital signal and delivers increased electromagnetic compatibility (EMC).
The “rapid recovery after saturation” is yet another unique characteristic. The analogue input stage is immediately reset when this function recognises an override brought on by a malfunctioning operating situation.Their products, including the microspectrometer with an integrated MOEMS-based Fabry-Pérot filter, which is currently a market leader, illustrate their expertise.
Additionally, it has distinguished itself in the optical sector and received various awards.To prepare for future demand and be ready to respond to emerging trends, such as the use of microsystem technologies, they continuously expand their development team as the market expands (MOEMS). In addition to creating products for their clients, they collaborate with numerous project partners and work on promotion initiatives for upcoming iterations of infrared sensors.
With plastic chip carriers, InfraTec hopes to further enhance its detectors in the future. For many years, InfraTec has used chip carriers made from metallic parts with contour etching for its pyroelectric infrared detectors. The components that are only a few millimeters in size don’t always conform to the specifications in terms of shape and dimensions.
Additionally, modifications to the actual design may result in unforeseen modifications to the detector’s characteristics. As a result, during production, waste and inspection work both significantly increase. Here, alternative chip carrier manufacturing processes may yield more reliable outcomes.
Therefore, InfraTec is doing research on components made of injection-molded metallic plastic with financial assistance from the European Fund for Regional Development of the European Union.
