How to shrink a Raman spectroscope and analyze complex samples on-the-go?

Thanks to a new concept – based on silicon photonics and thousands of tiny interferometers – Raman spectroscopes can be minimized to the size of a smartphone. Unlike existing handheld devices, this new concept exhibits the high optical throughput and spectral resolution of the desktop systems. This opens up a whole new range of applications in which complex samples can be analyzed with an affordable handheld device.
