Abstract

Nanohmics has recently developed a compact tunable filter for the longwave infrared that is based on a novel tunable plasmonic metasurface. Due to its high throughput, we are pursuing multispectral imaging on uncooled detectors that would normally be too light starved to operate with typical bandpass filters. We will present preliminary demonstration datasets and our progress integrating the filters with handheld imaging systems.
