Tiny tech
When I wrote my first article on portable spectroscopy not long after joining Electro Optics seven years ago, consumer devices started to be talked about, but more as a concept rather than a serious application. Some people I spoke to said they couldn’t see the performance of spectrometers ever being good enough to be of genuine use for consumers, or for their size to get down to a point that could be integrated into our everyday electronics. Now, thanks to developments in
Researchers have developed a program for outputting high-quality freeform optical systems that simply requires basic optical design knowledge

miniaturising optical components, as well as computing and integration, spectrometers are starting to exist at the chip level, and it’s seeming more likely that they will find their way into commonly-used consumer devices in the near future. Keely Portway on page 18 covers some of
