"When compared to meta-optics (MOEs), diffractive optics (DOEs) exhibit substantially higher stray light and lower imaging performance at low f/# and across temperature... 4x improvement in signal to noise in 3D imaging systems... Multifunctional optics replace an entire set of refractive lenses, resulting in lower cost of integration and assembly... Metalenses are fabricated with a single semiconductor layer for high yield, cost effective mass production"
