Curved detector: omg!

      Comments Off on Curved detector: omg!

Recent picture taken with our customized fish-eye optical system (optimization: Wilfried Jahn) The system has a 178 degrees field of view. Vignetting is mostly suppressed except for the very edge of the image. The system works with a convex sensor, full frame, 20Mpixels, produced by the CEA-LETI. The full optical characterization is ongoing and will be published by the end… Read more »

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 »
