The recesses are arranged to receive and retain projecting elements of a lens. Main elastic elements (30) e.g. compression spring or leaf spring, are arranged on a lateral wall of the base. Adjustment bolts (50) are arranged on another lateral wall, where the latter wall is opposite to the former wall. A pressure element (20) is firmly fixed on a front surface of the framework to support and retain the lens in the base.</p> |
