Video Spectrometer

This spectrometer is made with a black card inserts inside a 1" PVC or aluminum conduit box, and uses an HD USB webcam. This allows the user to view the spectrum in real-time, rather than taking a photo and analyzing it later. See a full bill of materials here:

This hardware design is released under the CERN Open Hardware License 1.1.

Specs

(these are approximated but we should soon post a page with calibration information)

• around 400-900nm, maybe wider
• 5-10nm spectral resolution
• 20-30 samples per second
• around $20 in materials, drops to around$10 if you use a really cheap webcam
• approx. 1 hour construction time
• web-based, open-source capture/analysis software at: https://spectralworkbench.org

Goals

Our early goals are to:
