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.
The writing in the linked article is a little weird, as others have pointed out. However the journal publication is very cool. If this is reproducible, it’ll likely have a noticeable impact over the next 10 years or so. We won’t see $10 spectrometers, but we might see handheld ones in a similar format to the cheap IR cameras.
Here’s the link for anyone interested.

If you’re familiar with this kind of stuff, do you think this could lead to cheaper and smaller hyperspectral cameras?
