Lens design is of paramount importance in the evolving world of technology, where compactness and high optical performance are a necessity. Freeform design techniques allow us to transcend traditional limitations, but creating new optics remains a substantial challenge unless we consider unconventional physical phenomenon. Researchers in France introduced a lens type based on freeform design, employing spiralization of one of its diopters that resulted in optical vortices. This enabled multifocality, primarily serving needs in ophthalmology; however, its potential applications could broadly impact many other domains. According to the researchers their lens design could be crucial in miniaturizing emerging technologies while retaining their optical quality… read more. Open Access TECHNICAL ARTICLEÂ
