We develop modules with UV light-emitting diodes which we adapt to the respective application and which can be optimally integrated into the advised overall irradiation system. Preference is given to the use of our own UV-LEDs, if necessary supplemented by LEDs from commercial suppliers. We have already developed UV LED modules for the disinfection of drinking water, of carrier fluid in flow cytometers and of surfaces in real-time PCR platforms for the identification of SARS-CoV-2.
The advantages of UV LEDs at a glance
- small, compact and robust
- can be operated at low voltages
- can be switched quickly
- do not contain toxic substances
Thanks to these properties, UV LED modules can be easily integrated into existing devices and are ideally suited for mobile applications. As a result, they are already superior to conventional UV radiation sources such as mercury-based gas discharge lamps in many respects.
Complete value chain in-house
- epitaxial fabrication of the semiconductor heterostructures by MOVPE
- chip technology in the process line of the FBH clean room and assembly of the chips in suitable packages
- fabrication of the electronic and mechanical components, their assembly and, if required, supplemented by optics
- characterization and qualification (e.g. radiation characteristics, degradation behavior as well as definition of ideal operating conditions)
In the UVdecon* project, we are working with our project partner to further develop an instrument system that identifies SARS-CoV-2 using real-time PCR testing and performs antibody tests. For existing purification units, we develop a suitable UV LED module to decontaminate the components of the instrument system by using 265 nm LEDs.
* UV LED for decontamination in detection systems
In the ULTRA.sens* project, photometric UV gas analyser’s based on UV LEDs are to be realized to detect gases such as nitrogen oxides, sulfur dioxide or hydrogen sulfur with detection limits < 1 ppm. For this purpose, we are developing in cooperation with the TU Berlin far-UVC LEDs (emission wavelength = 226 nm) with a sufficiently high efficiency and reliability for use in low-maintenance mobile gas analysers. We are also developing the LED emitter unit using LEDs of other wavelengths in addition to the far-UVC LEDs.
