I'd imagine it would be kinda accurate if you have any good reference sources like a He-Ne and maybe a He-Cd. Good Luck!

Found them on ebay, still not cheap though:

Although just found this, same sepctrometer but a DIY alignement kit for £120:

Put me down for two if they are 460nm and have equal or better specs than 445s.

I've got one of those science-surplus spectrometers and I highly recommend them.

Recklessly interfering with Darwin’s natural selection process, thereby extending the life cycle of dim-witted ignorami; thus perpetuating and magnifying the danger to us all, by enabling them to breed and walk amongst us, our children and loved ones.
I haven't really been following this thread, but if you need diodes tested I still have my wavelength rig running, which uses a usb650 spectrometer (still in cal from ocean optics) and can test whole arrays at a time.
