Desktop Spectrometry Kit

Buyers outside the US, Canada, EU, Japan, Taiwan, S. Korea please select USPS Priority International. Some international buyers may see additional import fees upon arrival.

Now shipping! The Public Lab Desktop Spectrometry Kit 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 (a slice of a DVD-R)
  • a piece of black card paper from which to cut your aperture slit
  • a small HD webcam and USB cable
  • an aluminum Type LB conduit enclosure
  • a strip of double-sided foam adhesive for mounting your webcam
  • instructions and a copy of the CERN Open Hardware License

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. You can help to improve it and find new applications!

For a smaller, cheaper spectrometer you can fold out of black card paper and attach to your smartphone, see the Foldable Mini-Spectrometer!

Actual webcam model may vary, but will be 1280x720. Please allow 2 weeks for shipping. All Public Lab content is CC-BY-SA and CERN OHL 1.1
