IndiGo : An affordable, modular spectrometer connected to a smartphone

IndiGo is a totally new generation of visible spectrometers. It is a compact modular spectrometer connected in Bluetooth to a smartphone. It allows the user to measure emission, absorption or transmission spectra from 370 nm to 810 nm with a resolution of 5nm. IndiGo is compatible with all the smartphones equipped with a Bluetooth 5.0 connection. 

Thanks to its dedicated app available on Android 7.0 (soon on iOS), it allows the user to make measurements anywhere, at anytime at a reasonable cost.
