摘要 | The method comprises a step of contactless optical measurement of the local value of at least one refringence optical characteristic of said lens over defined local zone around said measurement point of said lens, and at least one step of feeling said lens during which the axial position of said measurement point on one of the faces of the lens is determined; the axial position of the measurement point obtained by feeling is compared with the local value of the optical characteristic of the lens at the measurement point as determined from the contactless optical measurement, in order to deduce therefrom at least one vertex optical power of the lens at said measurement point. |
其他摘要 | 该方法包括在所述透镜的所述测量点周围的限定局部区域上的所述透镜的至少一个折射光学特性的局部值的非接触光学测量的步骤,以及感觉所述透镜的至少一个步骤,在该步骤期间所述透镜的轴向位置。确定所述镜片的一个面上的测量点;将通过感觉获得的测量点的轴向位置与从非接触式光学测量确定的测量点处的透镜的光学特性的局部值进行比较,以便从中推导出透镜的至少一个顶点光焦度。说测量点。 |
主权项 | A method of measuring the local power of an ophthalmic lens at a measurement point, the method comprising a step of contactless optical measurement of the local value of at least one refringence optical characteristic of said lens in a local zone defined around said measurement point of said lens, the method being characterized in that if further comprises at least one step of feeling said lens, during which the axial position of said measurement point on one of the faces of the lens is determined, and in that the axial position of the measurement point as obtained by feeling is combined with the local value of the optical characteristic of the lens at the measurement point as determined from the contactless optical measurement, in order to deduce at least one vertex optical power of the lens at the measurement point. |
