    This may be of some interest...

    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!

    $550 also.

    I'm going to make another DIY spectrometer in the next week; hopefully the CCD method will be more accurate - thanks 300Evil!

    Found them on ebay, still not cheap though:

    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.

    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. For my findings on A130 projectors see http://www.photonlexicon.com/forums/...f-A130-vs-A140
