Abstract

An optical device comprising at least an optical element having a cut away area and which supports an inner mechanical structure accommodated in the cut away area, the whole being supported by an outer mechanical structure without obstruction in the optical path between the structures. The contact areas of the optical element with the structures comprise mechanical gripping and position means including deformable members for holding an unvaried centered position to the optical element for severe temperature and mechanical operating conditions.
