I need to get a rough spectrum of a light.
Anyone know of chips which analyse light? Are there any?
In alternative: color CCD chips?

in astronomy afaik they use linear image sensors (like used in faxes and scanners) combined with prisms or diffraction gratings.
will give you a three-band "spectrum"
same effect could be got with three photodiodes and colour filters.
A prism or diffraction grating and a linear monochrome CCD sensor ought to give you a decent spectrum.
