Method Of Manufacturing An Optical Lens |
| 摘要 |
Method of manufacturing an optical lens, the method comprising: a lens member providing step (S1) during which a lens member comprising a first surface and a first reference system identified by first markings on the first surface is provided, a surface data providing step (S2) during which surface data corresponding to a second surface and the position of the second surface relative to the first surface of the optical lens are provided, a blocking and machining step during which the lens member is blocked and the second surface is machined, a second markings providing step during which second markings identifying a second reference system of the second surface are provided, a comparison step during which the relative positions of the first and second surfaces are compared. |

1. A method of manufacturing an optical lens, the method comprising:
a lens member providing step during which a lens member comprising a first surface and a first reference system of the first surface is provided, the first reference system being identified by first markings on the first surface; a surface data providing step during which surface data corresponding to a second surface and the position of the second surface relative to the first surface of the optical lens to be manufactured are provided; a lens member blocking step during which the lens member is blocked in a machining position; a machining step during which the second surface of the optical lens is machined according to the surface data; a second marking providing step during which second markings identifying a second reference system of the second surface are provided on the second surface of the optical lens, a reference system determining step during which the first and second reference systems are determined by measuring the positions of the first and second markings; and a comparison step during which the positions of the first and second reference systems are compared so as to estimate the positioning error between the first and second surfaces. |
