When illumination is made by LEDs, a powerful collimation lens is required. Traditionally these flash Fresnel lenses are manufactured by injection molding which is vulnerable to tool wear, inadequate feature size of circular Fresnel structures and poor replication accuracy. Nanocomp offers truly impressive solution for camera flash lenses, NAFLENS. NAFLENS has clear performance improvement compared to traditional lens solutions.
