Spectronic 20

[Jeffrey Warren]

I have this 1950's era Spectronic 20 visible range spectrometer:

As the Oil Testing Kit Public Beta moves forward, we're looking for a calibrated spectrometer to test the PL Desktop Spectrometry Kit against. I wonder if this could work.

Here are some operating instructions: http://web.nmsu.edu/~kburke/Instrumentation/Spectronic_20.html

I guess we need to know:

* if it's still calibrated and/or how to recalibrate?

* how to get laser light inside instead of the provided incandescent bulb (there's a hole in the bottom though so it shouldn't be too hard)

It's not a great spectrometer, but it's a standard instrument and could be a good basis for comparison.
