Title: Innovations by Erik A Larsen in Ophthalmic Lens Polishing
Introduction
Erik A Larsen is an accomplished inventor based in Seattle, WA (US). He has made significant contributions to the field of ophthalmic lens polishing, holding a total of 3 patents. His innovative approaches have advanced the methods used in lens manufacturing and polishing.
Latest Patents
One of Erik's latest patents is a surface polishing method and apparatus. This invention involves a lens held by a vacuum lens holder, where a lap wall is moved towards the lens surface while in a plastic state. A polishing fabric is positioned between the lens surface and the lap wall before they are moved together. Fluid pressure in a chamber behind the lap wall is utilized to move the lap wall and the polishing fabric against the lens surface, allowing the lap wall to take a shape corresponding to the lens surface. Once solidified, the polishing fabric moves relative to the lens, effectively polishing it.
Another notable patent is the castable ophthalmic lens polishing lap and method. This invention features a single castable ophthalmic lens polishing lap that includes a mounting plate for connection to a lap press/cylinder machine. The lap consists of a flexible membrane filled with castable material and a polishing pad affixed to it. The lap is created by applying energy to the castable material, causing it to soften and deform to match the lens's prescription curvature. After polishing, the lap can be recast for lenses with different prescriptions.
