Research and Development in Sensor Technologies
Permanent research and development of new sensor technologies are indispensable in order to meet the customer’s expectations as well as our own detector production requirements. Our developers are very experienced in the fields of electro-optical and electro-mechanical design, pyroelectric materials and signal processing electronics. This knowledge is the basis for developing innovative products as well as for the optimisation of applied production technologies and further development of our extensive measurement techniques.
We permanently increase our development’s workforce as the market is growing, in order to prepare for future request and to be able to react to newest trends, such as the application of microsystem technologies (MOEMS). In addition to product developments for our customers, we also cooperate with different project partners and work on various promotion projects for future infrared sensor generation.
Our know-how is reflected in our products, such as the digital detector (PyrIQ) for easy system integration, which is currently one of the competition-leading innovations.
Development of a Chip Holder in Silicon Micromechanics for Pyroelectric DLaTGS Detectors
As part of an innovation program with financial support from “Sächsische Aufbaubank” and the EU's European Regional Development Fund, the partners InfraTec and the Center for Microtechnologies at Chemnitz University of Technology have developed a chip holder for pyroelectric DLaTGS sensor elements.
DLaTGS as a pyroelectric material can be used to build detectors that meet the very highest signal-to-noise ratio requirements. They are therefore indispensable for certain applications such as FTIR spectrometers. At the same time, the DLaTGS material places the highest demands on processing and handling, as it is water-soluble, fragile and sensitive to temperature. Consequently, the chip holder must be optimized to meet very specific requirements, which result from the application (FTIR) as well as the material properties of DLaTGS.
The solution developed by the partners is based on silicon micromechanics (MEMS technology). Different variants were designed, manufactured and successfully evaluated.
InfraTec develops and manufactures high-performance detectors as well as special solutions that meet the highest requirements.
KERAMIR – Monolithic Ceramic IR Emitter
New type of thermal emitters with extra power and reliability
In the KERAMIR project, the partners InfraTec and the Fraunhofer Institute for Ceramic Technologies and Systems IKTS, with financial support from the European Regional Development Fund of the European Union, want to establish the technological foundations for a completely new category of ceramic-based IR emitters. These emitters should be characterized by a high radiation power in the mid and far infrared range, excellent long-term stability of the optical and electrical properties, high reliability and long service life as well as a very compact surface-mountable design. Ceramic multilayer technology is used to meet these sometimes conflicting requirements. As a result, the IR emitter can be realized as a completely monolithic ceramic component. The key innovation is that the radiating surface is designed as a thin self-supporting ceramic membrane in combination with a thin metallic layer.
