What is Spectral Workbench?

SpectralWorkbench.org is a web based application to collect, archive, share, and analyze spectral data, for Public Lab DIY spectrometers and other spectrometers.

With it, you can:

• connect your USB Desktop Spectrometry Kit
• 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

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.

Development

Do you code? The codebase of Spectral Workbench is available at https://github.com/publiclab/spectral-workbench. The server is written in Ruby on Rails, with a lot of client side code in JavaScript. You can read about the JavaScript API here.

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
