"FrinGOe uses innovative crystal technology to create a low cost 2D array of Mach Zehnder Interferometers and patented optical configuration to map the array onto the camera sensor. This allows an all-passive and compact optical add-on (as small as 4mm by 4mm by 2mm) that can be mounted onto any imaging platforms such as a mobile phone camera, Raspberry Pi camera or other OEM devices." One of the prototypes of the FT spectrometer has a spectral resolution of ~1 nm @ 400nm wavelength.

and imaging modes
In June, the company plans to launch FrinGOe at the Laser World of Photonics (Munich) exhibition and at the same time start an Indiegogo campaign to kick-start the mass production efforts. FrinGOe's Youtube video shows the spectrometer operation:
