Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers laboratory-grade precision in a device small enough to be embedded in portable and wearable technologies. By rethinking how spectra are measured and processed, the team has demonstrated a spectrometer costing only around $10, operating at a centimeter scale, and capable of applications ranging from industrial quality control to real-time health care monitoring.
Yes, there is a lot of potential. There are micro-spectrometers available covering this range, like the MEMS-FPI type spectrometer or the multi-pixel arrays with filters (example: https://www.mantispectra.com/products). But this new kind of detector seems to come with higher resolution, faster readout than the MEMS-FPI, and more sensitivity. It is quite exciting, I’m curious to see if they commercialize it soon.
