Curved detectors: First images!

      Comments Off on Curved detectors: First images!

This picture, 135 degrees Field of view, was obtained out of a fish-eye like objective made of 9 lenses and 3 materials. Compared to the existing systems, we gain about one third of the optics and reduce the number of required materials of about 70%. The custom fish-eye objective made of 9 lenses, only spherical surfaces, and using the curved… Read more »

Curved detectors: first concave prototype delivered!

      Comments Off on Curved detectors: first concave prototype delivered!

Our brand new prototype of a concave curved detectors has been delivered at LAM this week! This full frame, fully-functional, 20Mpixels concave CMOS detector perfectly works in the visible. With a radius of 150mm over a size of 24x32mm², such a breakthrough device will allow to drastically reduce the amount of lenses required in wide field imaging systems, as well… Read more »

      Comments Off on H2020 OPTICON program successfully evaluated

Breaking news! The OPTICON network proposed in the frame of the European Horizon 2020 program has been successfully evaluated by the commission. This European project gathers 32 institutes and will cover the period 2017-2020. Several members of the group are involved in five different work packages related to our activities: adaptive optics, innovative detectors, freeform mirrors metrology, additive manufacturing for… Read more »

FAME: the very first Freeform Active Mirror

      Comments Off on FAME: the very first Freeform Active Mirror

FAME stands for Freeform Active Mirror Experiment, and is a four years effort of the European community to produce the first ever active freeform mirror, that has been presented in June 2016 at the SPIE symposium on Astronomical Telescopes and Instrumentation in Edinburgh. This amazing achievement is a breakthrough pathfinder towards innovative active optical concepts that will make use of… Read more »
