Multispectral Filters for MIR Spectral Imaging Applications
2022 ASIA COMMUNICATIONS AND PHOTONICS CONFERENCE, ACP(2022)
Abstract
This paper presents novel multispectral filters (MF) for spectral imaging applications with mid-IR (MIR) wavelengths. The metasurface-based filters are fabricated with conventional micro-nano fabrication facilities and exhibit bandwidths less than 250 nm and maximum transmission efficiencies of around 60%. The filters show promise for applications in precision agriculture, medical imaging, gas sensing, and other areas.
