Apparatus for measuring the refractive power of ophthalmic lenses by combining a non-contact measurement and the whole transducer

摘要

A method of optically measuring the non-contact local value of the refractive optical properties of one method, at least one for probing the lens at least in a zone localized defined around the measuring point of the lens and comprising the steps of Tsu, at the stage touch , is determined from the non-contact optical measurement axis position of the measurement point the axis position of the measurement point on one side of the lens is determined, obtained by probing Compared to the optical properties of the lens at the measurement point was, the vertex optical refractive power of one is calculated at least the lens at the measurement point.
