Plastic lens generator and method. |
摘要 |
<p>The generator for plastic lenses comprises a rotatable chuck (96) for rotating an optical lens blank (86) on a first axis. A drive system displaces the chuck and thereby the lens blank generally transverse to the first axis. A cutter (56) is operably associatable with the chuck for engaging the lens blank and causing shaping thereof. The cutter includes a high speed rotary element rotatable on a second axis angularly disposed relative to the first axis. A second drive system for selectively displacing the cutter parallel to the first axis is provided. A computer control is operably associated with the first and second drive systems for coordinating displacement of the associated chuck and cutter for causing a selected curvature to be generated on the blank. <IMAGE></p> |
