Interesting- did you google it?

The sensor is a linear one - you put in a clock signal and it gives an analogue output of each pixel- they must be using a prism or diffraction grating to separate the spectra. You could almsot make one yourself.. Datasheet Here.

Youtube vid of someone pointing a laser pointer at the poor innocent sensor... OK I can't get youtube embedding to work...
Here is the link to it.

The sensor is basically the same one you find in a typical flatbed scanner. Horizontal CCD sensor.

Interesting kit.

Ohh nice, that thing is expensive too!

Thankfully, it was donated :thanks: after the owner of the company who purchased it retired -- God knows I'd never be able to afford one of those critters on my meager disability stipend! :can:
