Enabling the common use of curved detectors will revolutionize the way instrumentation is conceived. By directly correcting the field curvature on the detector,  the gain in terms of number of optics, weight and throughput  is drastic (up to 30%). The activities undertaken so far tend to prove the feasibility of VIS or NIR detectors with significant curvatures (typically 300mm-1).

The on-going project I lead in close collaboration with the CEA-LETI and with the support of the OASIX ANR and the FOCUS LabEx opened new windows that are now part of the ICARUS ERC proposal. The main objectives are the following:

  • Propose new paradigms in the way instrumentation is conceived through extensive optical simulations
  • Enable  a common use of  curved VIS and NIR detectors arrays with the demonstration of  performance with prototypes
  • Pave the way to a mass production of curved detectors and address promising markets.

Delivery of the first fully functional, full size prototype of a highly curved CMOS sensor.
