Lumetrics has just published a research paper at a peer-reviewer journal Optics Express. The paper summarizes work Lumetrics has conducted in collaboration with Johnson and Johnson in the past 1.5 years. We have developed a measurement approach for the bulk phase refractive index of hydrogel and silicone hydrogel (soft) contact lenses in solution at multiple wavelengths with an accuracy of+/- 0.001, and sensitivity to change of 0.0002. The method uses time-domain low-coherence interferometry to obtain group refractive index (GRI) for contact lenses between 530 to 670 nm in 10 nm increments. The measured GRI dispersion curve is then mathematically converted to the phase refractive index values. The approach is based on a point measurement using focused beam, and therefore does not require flattening of the lens for the measurements. We discuss practical implications to use this method for quality control in the manufacturing of ophthalmic optics.
