Abstract
The device for polishing optical lenses includes a lens holder; a device for positioning the lens holder; and a device for rotating the lens holder about an axis. There is also a polishing tool; a tool holder; a device for positioning the tool holder; and a device for rotating the tool holder about an axis. The device for polishing also includes a ball joint arranged between a shaft secured to the tool holder and the device for positioning the tool holder, or between a shaft secured to the lens holder and the device for positioning the lens holder, so as to enable a spherical movement of the polishing tool and of the lens. The invention also relates to a method for polishing using the device according to the invention.
