Public Lab is an open community which collaboratively develops accessible, open source, Do-It-Yourself technologies for investigating local environmental health and justice issues.
###What is Spectral Workbench?
[SpectralWorkbench.org](https://spectralworkbench.org) is a web based application to collect, archive, share, and analyze spectral data, for Public Lab [DIY spectrometers](/wiki/spectrometer) and other spectrometers.
With it, you can:
* connect your USB [Desktop Spectrometry Kit](/wiki/desktop-spectrometry-kit-3-0)
* scan and save samples
* wavelength calibrate your spectrometer
* plot light intensity as a function of wavelength (average digital consumer cameras have a range of 400 to 700 nm)
* create sets of multiple spectra to visually compare and analyze scans
* download CSV data for offline analysis
* view others' data and discuss
* find similar data in [a database of over 60k spectra](https://spectralworkbench.org/stats)
No download is required -- just a web connection. The Chrome browser works best, but most standard-compliant browsers are supported. It is possible to use from an Android smartphone, preferably with the Firefox browser which allows you to specify which camera to look through.

Spectral Workbench should work on Chrome (in Windows/Mac/Linux/Android, but not iOS), Firefox (Windows/Mac/Linux/Android), or Opera (Android). It may work on other browsers and we are working on expanding coverage; read more on this page:
We really need more developers, so if you are interested, please get involved! A great place to start is the "plots-dev" mailing list for software developers: http://publiclab.org/wiki/developers
We're collecting and working our way through a range of questions about Spectral Workbench -- if you can contribute your own questions, or answer others', please do!
If you feel you've encountered a bug with the software -- very possible! Please look through existing issues listed here, file a new one if you don't see something similar, and help to add any observations to existing issues shown here.
Thanks for helping improve this open source software!
