Corning Diamond Turning

A firm which believes 'Almost Accurate' is Not Good Enough When the famous Swiss archer William Tell shot the apple off his son's head he was heard to say - 'almost accurate is not good enough'. Corning Diamond Turning is a company that believes this and performs to this standard everyday. Precision is a term ordinarily associated with precision optics and not ophthalmic lenses. However, today with high index, aspheric, and more and more sophisticated progressive lenses, precision has become a necessary and important part of ophthalmic lens making. Corning Diamond Turning is a company known for its precision optic expertise and is now using those resources for the ophthalmic lens industry. An entire business unit is dedicated to manufacturing precision optical mould inserts for the injection moulding of lenses, including lenses moulded for ophthalmic, sunglass, and sport use. Manufacturing to exacting standards is essential in the production of lenses. Corning has the technology and the know-how. The technology is diamond turning on innovative CNC lathes and advanced proprietary computer programs that control it. The know how comes from years of experience in precision optics that demands accuracy measured to nanometers. A nanometer is one one-millionth of a millimeter. This kind of accuracy when used for progressive lens mould inserts produces mould inserts that are a perfect replica of their theoretic designs. Lenses moulded with Corning inserts will not vary from their original design characteristics or from each other from moulding to moulding. As new generations of progressive designs come to the market with better and better optics, the accuracy of the lenses moulded is more and more essential.
