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/near-infrared spectrometer, also known as a spectroscope or spectrophotometer.
For a more rigid, robust tool, try the Desktop Spectrometry Kit, which is made of more sturdy construction and is designed to last.
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. Read about more on that page about what spectrometry is for, what we can do, and what its limitations are.
