Open Fiber Spectrometer

cults3d

This is a low cost yet quite functional 3D printed spectrometer with an optical fiber link. The low profile case is completely 3D printed including a connector for an optical fiber cable (Toslink, same as used for audio devices). The fiber is really practical to measure the optical spectrum in the visible range in many situations. The spectrum is picked up by a recycled laptop camera with USB connector soldered to it. And as a diffraction grating the 1000 lines/mm Grating Slide from ebay are used. For more information see: http://www.gaudi.ch/GaudiLabs/?page_id=825
