Lightfinder

Lightfinder develops chip-scale spectrometers and imaging systems that deliver lab-grade optical sensing in a miniaturized, scalable form. Built on silicon photonics and paired with intelligent software, the platform enables real-time, in-situ analysis in places legacy instruments can’t reach—from inside semiconductor process tools to the factory floor—powering critical decisions in advanced manufacturing, telecommunications, and beyond.
