Papercraft Spectrometer Intro Kit
The Public Lab Papercraft Spectrometer folds up in minutes to transform your smartphone into a compact, simple, experimental tool -- a visible light spectrometer, also known as a spectroscope or spectrophotometer. Using the Papercraft Spectrometer, you can determine the composition of a light source by examining the spectral pattern of light that passes through a diffraction material, visualized on the screen of your phone as a rainbow. Just take a picture of the resulting spectra image on your phone and upload that photo to SpectralWorkbench.org to compare to known spectra and draw conclusions about what may or may not be present in your sample.
To find out more about spectrometry, how to calibrate your tool, or what discoveries other community scientists have made, check out publiclab.org/wiki/papercraft-spectrometer.
This introductory kit has been co-designed by hundreds of contributors as an entry point to Public Lab's collection of Do-It-Yourself spectrometry projects.
