Claim Text:
1. Apparatus for measuring a physical characteristic of an ophthalmic device, the apparatus comprising: an optic mandrel for forming an ophthalmic device using free-form technology; said optic mandrel comprising an optical effect; a lens cancellation system comprising one or more lenses to collectively cancel said optical mandrel's optical effect; an emitter functional to emit a wavelength of radiation in a direction towards the ophthalmic device; a sensor functional to detect a transmitted wavefront based upon the emitted wavelength, wherein the transmitted wavefront's intensity and phase will be different based upon a physical characteristic of said ophthalmic device, and a processor in logical communication with one or both of the emitter and the sensor; wherein the processor is programmed to transmit a logical signal based upon the reflecting wavefront's intensity and phase.
