Abstract

Ingenio/SEOSAT is a multi-spectral high-resolution optical satellite for Earth remote sensing, designed to provide imagery to different Spanish civil, institutional and governmental users, and potentially to other European users in the frame of GMES and GEOSS. In this communication is presented the developed shimming procedure for the light-weighted primary mirror (M1) of the Ingenio/SEOSAT telescope, together with obtained results. The shimming operation has been devised to accurately cancel the residual deformation on the mirror surface caused by its integration on the telescope structure. This deformation is generally small but not necessarily negligible; even if all elements are integrated using proper isostatic mounts.
