High-resolution metalens doublet microscope enables compact biomedical imaging

Metalenses represent a revolutionary advancement in optical technology. Unlike conventional microscope objectives that rely on curved glass surfaces, metalenses employ nanoscale structures to manipulate light at the subwavelength level. Thanks to their ultrathin, lightweight, and flat architectures, metalenses can overcome the bulkiness of traditional lenses, making them ideal candidates for integration in electronic devices and compact imaging systems.
