Abstract : A lens of an optical system in space to be moved, and thereby be focused, resulting in the focusing of the system. The lens is mounted, in a diaphragm of resilient material, with a ring-like component made of magnetic material. An electromagnet is positioned on either side of the lens and of the ring-like component. Application of d.c. current, by remote control, through the electromagnets, causes the translational movement, and the necessary focusing, of the lens and, therefore, of the optical system. (Author)
