Public Lab Spectrometer 3.0

This is the latest version of Public Lab's Desktop Spectrometer. The Public Lab Desktop Spectrometry Kit 3.0 includes all the parts for a compact, simple, yet powerful experimental tool -- a visible/near-infrared spectrometer, also known as a spectroscope or spectrophotometer. In less than 30 minutes of assembly, you can plug it into your computer with a USB cable and begin using the SpectralWorkbench.org software and website to collect spectra -- the "fingerprint" of a material. The kit includes: • a diffraction grating (you cut from a DVD-R) • an acetate collimation slit • a durable, ultra-black, papercraft enclosure • rigid and adjustable mounting board • printed instructions and online documentation • webcam and USB cable • wooden mounting block • 1 roll of double-sided super tape Developed by Public Lab contributors, this open source instrument is capable of better than 3 nanometer spectral resolution and can record light from ~390 to ~900nm. Though experimental, this tool has already been used to collect spectral data on contaminated water, laundry detergent, wines, and fishtank lights.
