Abstract[English]
A wide-angle lens optical system comprises, from the object side to the image side, a focusing lens group (FG) with a positive refractive power and a fixed lens group (FL) with a negative refractive power. The focusing lens group (FG) is movable along the optical axis for focusing while the fixed lens group (FL) is fixed on the most image side adjacent to the imaging surface (IMG) so that the back-focus is also fixed.[French]
Un système optique à objectif grand angle comprend, du côté objet au côté image, un groupe de lentilles de focalisation (FG) ayant une puissance de réfraction positive et un groupe de lentilles fixes (FL) ayant une puissance de réfraction négative. Le groupe de lentilles de focalisation (FG) est mobile le long de l'axe optique pour la focalisation tandis que le groupe de lentilles fixes (FL) est fixé sur le côté image le plus adjacent à la surface d'imagerie (IMG) de telle sorte que la mise au point arrière est également fixe.
