Description
Eunji Lee and Junsuk Rho highlight in 2026 a wafer-made lens pair that gives near-infrared cameras a very wide view in a tiny package. Flat metalenses can steer light with surface patterns thinner than a hair, yet single layers struggle to fix image flaws at wide angles. Pairing a shaped glass lens with a patterned metalens splits the correction work between them.
The highlighted device reaches a field of view just over one hundred degrees in a stack only a few millimeters long. Both parts are made on wafers and bonded together with precise alignment, then cut apart in one step. An air gap shields the fine surface patterns during bonding. Mass production without hand alignment could suit eye tracking, face checks, and vein imaging.
