LUMOS-V
Precision Measurement of Refractive Index for Soft Contact Lenses
Accurate refractive index knowledge of soft contact lenses is critical for lens performance evaluation. The LUMOS-V sets a new standard which is an order of magnitude more precise than the current Abbe refractometer methodology.
Lumetrics’ expertise in low-coherence interferometry led to the development and patent of multi-spectral low coherence interferometry (MSLCI) which provides an RI accuracy of .001 and allows for a bulk material RI characterization accuracy of +/- .001 with a sensitivity of .0002.
Lumetrics collaborated with Johnson & Johnson MedTech (Vision Care) on this new approach to measuring RI with unprecedented precision. This was a multi-year effort that went from prototype to now what is a commercially available system.
MSLCI is a significant advancement in contact lens metrology. Every contact lens manufacturer and their patients will benefit from the ability to better characterize contact lens material.
