If you are serious about doing this right then a 2D CCD sensor and a prism hires grating combo at right angles will allow you to quantify the entire visible spectrum at ultra high resolution.

eons ago we used some CCDs as detectors for X-ray fluorescence, some had weird formats like 1024x64 pixels so I assume they were really made for spectroscopy

As mentioned elsewhere, how do they fare when light is shining directly on the
sensor? How do you keep it from saturating -- dark lens to attenuate the signal?
You vary the exposure to avoid spillover.
You can only use an electronic shutter to a limited degree. You still
have to worry about protecting the sensor from being "cooked". I.e.,
a mechanical shutter (something best purchased as silly to try to design)
