EU-funded PHENOmenon project comes to an end with great success


After 3 years and 4 months of intense work the EU-funded PHENOmenon project ( came to an end with great success in April 2021. Multiphoton Optics was one of 12 partners in this project which concentrated on the development of materials, processes, and technologies for high-speed fabrication of optical structures via two-photon absorption. Multiphoton Optics’ focus in the project was on testing the newly developed materials and on implementation of parallelization techniques for increased throughput. The company has also supported other partners’ efforts in achieving their project focus goals.


Clear imaging in environments with highly humid conditions

One application of the developments made in the project could be to improve the performance of imaging systems in environments with high humidity (rain, fog). The antifogging demonstrator presents a solution approach for thermal imaging. In humid environments fogging up of the optical system may cause severe issues, because thermal radiation is strongly absorbed by humidity.

For this purpose, Multiphoton Optics has structured an area of 1 cm² with photoresist in the center of a Germanium window. The ultrasensitive photoresist was developed by CNRS in course of the project. Thales provided the specifications for the structures which create the superhydrophobic effect (see picture).

The water repellent effect prevents the window from fogging up in moist environments. Mounted in front of a thermal imaging camera, the structured antifogging window ensures that a clear thermal image is displayed.



We would like to thank the project partners for the excellent cooperation and great results, making PHENOmenon a successful project.
