Spectrographic analysis of a 5mm SiC (silicon carbide) blue LED, circa. ~1995.
If (forward current) was ~150mA for this test so that I could get an acceptably high reading.

What type of hardware and software do you recommend for performing such analyses?

I use pretty much what was provided to me.
In this case, a USB2000 spectrometer from Ocean Optics ($2,999.00) and SpectraSuite operating software, also from Ocean Optics ($349.00).

I have no other recommendations to offer here, simply because I have not used any other hardware except for a Spectroscopic and Analytical Developments (SAD) spectrometer, which I had functional for a brief period just after the turn of the century. It was ok, but certainly not up to the same standards that the USB2000 is.
