Spectrosmart. Ou comment transformer votre smartphone en spectroscope.

thingiverse

This device allows for the collection of spectra from objects in re-entry into the atmosphere in order to determine their composition. Any other light source can be analyzed. It's a sort of filter composed of "pieces with a nanorainuré film stuck on (500 lines per mm2)." Intended to be stuck in front of your smartphone's lens, it will always be in place. Its drawer allows you to select or not the filter and won't hinder the use of the phone or camera in standard mode. A parametric base is available (file 3) for lenses with protrusions. File 1 (case) should be printed twice. A user manual for assembly and use will soon be available on the site: http://www.savoir-sans-frontieres.com In French and English language http://www.jp-petit.org/bonnettereseau.htm http://www.jp-petit.org/ufospectrum.htm
