UV curing formulations with high RI for microlenses

This project is about the investigation of prospective high refractive index (RI) polymer materials for use in graded refractive index (GRIN) microlens. An aliphatic polyurethane diacrylate was combined with three different zirconium acrylates containing one, two or three acrylate groups in differen...
