Measurement of contact lens can performed with the high resolution PhaseView's Digital Wavefront Camera (DWC®) and GetWave® software. The advantage of PhaseView's customized systems, compared to scanning techniques, is that measurement time is short (of the order of one second), so it is suitable for on-line control during production. Also, DWC® can be used both for accurate measurement of the aberrations and for qualitative visualization of degree of cleanliness of the lens surfaces to a CCD pixel resolution in a production environment.
