Technology transfer on-track

      Comments Off on Technology transfer on-track

By directly correcting the field curvature, curved detectors open a new space for optical systems design. By allowing an optimisation of the focal plane curvature, these devices allow a reduction of about 30% of optics in wide field systems. CNRS is supporting our research by pushing forward the technology transfer program I initiated in the group on this technology. The… Read more »

Polishing challenges for large facilities

      Comments Off on Polishing challenges for large facilities

We had the great pleasure to organise one more edition of the polishing challenges for large facilities in collaboration with CEA CESTA on June 18-19 2015. The french community is deeply involved in large facilities realization in terms of polishing of precision optics. During these days, we reviewed the common needs and the work done so far for the following… Read more »

Delivery of the SPHERE active mirror module

      Comments Off on Delivery of the SPHERE active mirror module

So far, successful delivery of the SPHERE Active mirror module. The new motorized active mirror has been installed at the core of the instrument and alignments are on going, as well as calibrations. The team here is composed of Kjetil Dohlen (SPHERE system Engineer), Anne Costille (SPHERE CPI System engineer), my self, and GĂ©rard Zins working on the software part,… Read more »

Happy Birthday SPHERE!

      Comments Off on Happy Birthday SPHERE!

One year after the first light, we are still working on the instrument to enhance its performance. This week is dedicated to the in-lab integration of the SPHERE active optics module, namely the Active-TM3. Below you see the brainstorming results, the CAD models and the mirror before integration. The “Tiger team” is composed of Sabri Lemared, who designed the active… Read more »

Hubble’s 25th Anniversary

      Comments Off on Hubble’s 25th Anniversary

I had the great opportunity to attend the Hubble 25th anniversary Symposium at the STScI, followed by the amazing conference dinner where 2 Nobel prizes and 9 astronauts were attending, amongst all the bright smart scientists that were/are part of this fantastic space adventure. Back to my first times when I felt very little looking up at all these smart… Read more »
