I and my friend, want to build a spectrometer according to below graph

basic information to design and build spectrometer are:
signal level, Wavelength range, footprint and spectral resolution.

we don't know two of them and that are footprint and signal level

anybody can help us to find and understand them

thanks

we saw wikipedia, there isn't any useful information there.

You're joking I hope, you aren't going to build a spectrometer starting from that hideous grinning caricature of a flowchart. You might start with what you want to use it for, look at what's available commercially, and then decide whether or not you want to build one from scratch or just buy one.
 
Why are you wanting to build it instead of purchase one? Money issue? For fun?
