Shows a lens in a holder and a force pressing on it and causing a problem when not supported

Polishing thin lenses

For chemical-mechanical polishing of optical surfaces, a certain contact pressure between the polishing tool and the workpiece surface is necessary. It is determined via the polishing force FP and the tool size. If this pressure is not transferred on the entire surface of the workpiece holder, undesirable deformations in the workpiece can occur, which ultimately lead to shape defects. For …
