Thus the Scio should be a visual light instead of NIR spectrometer?<p>Or is it the phosphor blob required for spread-spectrum IR because NIR LEDs are too narrow bandwidth? (I may be showing my ignorance here...)</p></p>

On the hardware side, I think it's a 12-channel NIR spectrometer (as the pictures show here), that has a range of (I think) around 700-1100nm. The AS7263 sold by Sparkfun above is a NIR sensor with 6 spectral channels and an easy-to-use interface, and Hamamatsu has a number of exceptionally powerful and tiny microspectrometers with ~128 pixels over VIS/NIR spectral ranges for around $200 ( https://www.hamamatsu.com/eu/en/product/category/5001/4016/index.html ).</p>

If so you can purchase a used spectrophotometer off of eBay for about $200 which will do as much if not more.</p>
