Using their web-based software at spectralworkbench.org, a full function spectrometer with data capture can be achieved. They ...

The spectrometer design uses a color webcam simply because they are everywhere. I agree eliminating the Bayer filters and the quartet of sensors for each pixel would simplify things greatly. The camera software is open source, and there is a stand-alone java version I never used that may or may not ...
