Technical description:
The parabolic main mirror of the telescope alone does not produce a good image of the whole field of view, and so a WideField Corrector (WFC) is installed in front of the camera. 

The WFC has been designed at HIA (Victoria, Canada). The lenses have been fabricated by SAGEM/REOSC, which also built the mechanical structure of the WFC and coated the lenses. 

In this picture looking up through the lenses, the WFC is seen from the floor just before the lift of the upper end to the telescope. A succession of lenses and baffling rings ultimately extends to the mosaic of MegaCam.
