Chlorophyll Absorption Analysis Enabled by Silicon-Rich Nitride-Based Concentric Ring Metalens

Year: 2025

Type: conference-paper

Abstract: A silicon-rich nitride (SRN) concentric-ring metalens, operating at 685 nm, achieves measured numerical aperture of 0.5 and 36% focusing efficiency, enabling metalens-based chlorophyll absorption analysis and plant health evaluation for the first time.
