Abstract

Miroir focalisateur à focalisation réglable, notamment pour héliostat, du type comprenant une structure moulée en béton présentant une face de référence sur laquelle sont collés à faible distance les uns des autres, mais sans contact entre eux, de petits miroirs plans élémentaires, et un support solidaire de la structure sur laquelle sont collés les miroirs élémentaires, du côté opposé à la face de référence portant lesdits miroirs élémentaires et monté pivotant par rapport à deux axes perpendiculaires. Selon l'invention, le support solidaire de la structure moulée en béton Il comprend un cylindre en béton 147 recouvert d'un feuillard métallique capable de glisser sur de premiers appuis 143 disposés sur un plateau en béton 144 qui présente une surface inférieure de contact 148 en métal poli capable de glisser sur de seconds appuis 146 disposés sur un poteau fixe en béton 145. Le montage selon l'invention vise à accroître la stabilité et la précision des mouvements du miroir 1.
