Multispectral tunable filters with high performance are desirable components in various biomedical and industrial applications. In this Letter, we present a new narrowband multispectral tunable filter with high throughput over a wide dynamic range. It is composed from a wideband large dynamic range liquid crystal tunable filter combined with a multiple narrowbands spectral filter made of two stacks of photonic crystals and cavity layer in between. The filter tunes between nine spectral bands covering the range 450–1000 nm with bandwidth <10 nm and throughput >80%.

This was a genuinely insightful read, and I really appreciate you diving so deeply into the social dynamics surrounding narrowband multispectral applications. It's something I've observed too, and you've articulated it perfectly. Honestly, I didn't expect this post to be quite so informative; it's definitely a standout piece. The way you broke down the complexities made it so accessible https://www.esafety.gov.au/ I recall a time when I was wrestling with a project, and fully embracing this approach, or at least understanding its potential, truly felt like a turning point for my work. It’s great to see such generous content shared so openly. I'm already thinking about how to integrate these insights into our team's knowledge base because it’s that valuable. It…
