| Passive array of Mach Zehnder interferometers with path difference fixed at different values. |
"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.

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:
