I built lab grade NIR spectrometer around Arduino. At least first two prototypes of it, then graduated to Teensy (32bits compatible board) and will use custom board for production. The thing is: most of electronic projects needs some way to control things and it is great to take shortcuts. In my case all analog section was custom made to the point of 16bit ADC and used Arduino/Teensy as a way to react to clicks on button, transfer data to computer and stuff like that.
