At the end of 2017 our Project MIRACLE was funded by program Horizon-2020 by the team of 13 partners. art photonics‘ role in joint work will be to develop and provide flexible IR-fibers for QCL coupling with the distal end of arthroscopic probe.
artphotonics is the worldwide leader in Polycrystalline fiber technology for 4-16µm range and is the single OEM partner in MIRACLE consortium providing the flexible Mid IR-fibers for this promising project success.
MIRACLE (Mid-infrared arthroscopy innovative imaging system for real-time clinical in depth examination and diagnosis of degenerative joint diseases) will take towards commercialization the first mid-infrared (MIR) arthroscopy probe for in-depth evaluation of articular cartilage enabling early diagnosis of degenerative joint diseases such as osteoarthritis. This will be achieved combining three novel photonics components:
- a quantum cascade laser array tailored to biodiagnostics,
- an on-chip beam combiner for efficient radiation coupling, and
- MIR sensing probe for imaging.
The MIRACLE project joins 13 European partners from 6 countries, including research, industrial and medical partners: University of Oulu, Ulm University, University of Eastern Finland, Norwegian University of Life Sciences, Kuopio University Hospital, Utrecht University, nanoplus Nanosystems and Technologies GmbH, OptoPrecision, art photonics GmbH, Innovacio Recerca Industrial Sostenible SL, Instituto Nacional de Engenharia Biomédica, Asociación Española de Normalización, Photonics Finland.
art photonics is focusing on development of innovative MIR imaging-probe.
On June 19th, the “Education-Alliance-Adlershof” organized guides for students in innovative companies throughout Adlershof, Berlin. art photonics GmbH was part of the program for the first time and the two groups of students from schools all over Adlershof were guided through all areas of the company – from sales and logistics to production and quality control. The students had a chance to ask all kinds of questions and therefore gather a lot of information that they can’t obtain in high school. Though, of course, not every student was highly motivated, all of them enjoyed the insight into the companys workflow and some even showed special interest in certain areas.
The event is supposed to be a help for the students to make a career dicision, which is very difficult nowadays, considering how many excellent option are available. art photonics managed to represent a succesful company, with concrete aims and splendid work atmosphere.
Thermal injury is the most important mechanism of lesion formation during radiofrequency catheter ablation procedures. Irreversible tissue injury requires heating to approximately 50 °C. Temperatures above 100 °C result in coagulum formation. As temperature plays a major role during radiofrequency catheter ablation procedures, temperature monitoring has been recommended as a tool to help catheter ablation procedures. The results of recent clinical studies show that electrode temperatures do not vary at successful and failed ablation sites; electrode temperature does not predict or remove the possibility of arrhythmia recurrence [1].
Development of innovative fibers for mid-IR spectral range paves way for a number of promising fiber applications ranging from 2 to 18 µm. Many years of art photonics’ research and development for reliable IR-fiber technologies resulted in the final selection of the main IR-materials suitable for production of mid IR-fibers of optical performance acceptable for pragmatic applications.

To develop an online probe that is not only sufficiently robust, but also able to measure crucial process variables in biogas plants is a tough challenge. Therefore, a mid-infrared (MIR) spectroscopic attenuated total reflection (ATR) probe and robust probe fitting were established. A fully automated probe control, calibration after probe cleaning, and analysis of the absorption spectra using machine learning were implemented in order to reduce maintenance of the probe to a minimum. The relevant wavelengths in the MIR spectrum for organic acids, total alkalinity, and ammonium nitrogen concentration were identified. Finally, intensive lab testing was carried out, followed by operation of the complete online measurement system at an industrial biogas plant. In order to improve signal strength and sensitivity, microelectronic mechanical system (MEMS)-based Fabry-Pérot interferometers were also investigated.
