Supply front. It has an on off switch and an ammeter to indicate primary high voltage draw. Deuterium lamps must be started with a heater and a spark, so the trick of these supplies is to kick that w/o damaging the lamp. The yellow light comes on for about 5 or so seconds to fire the lamp, and the arc stabilizes in about 5 more to the usual "uv" violet glow.
from the top of the source housing
bottom of the housing type also 33-66-35
output aperture from supply (operating, but flash and exposure doesn't show uv)
uv purple, available light shot.
collimation lens system. since it is UV, must be quartz optics
Next stop, collect the monochromator from stash and test out the thing. Unfortunately, I don't know how far down my Ocean Optics spectrograph goes.
