More experimenting, not sure if any of these spectrums are any good.

Yes, quite good!

The yellow line on the right is actually two lines quite close together. If you narrow the slit a bit, they should resolve.

If you can get the dark line between them you have obtained a high enough resolution for 95% of lamp spectra!


You have got the dim 510nm (emerald green) mercury line right in the middle of the picture very well.


Off to the left, down in the deep violet, there are two more lines at 407 and 404nm, they are quite difficult to photograph...not because the camera can't see them, it is just because they usually fall outside the camera's width of view and panning over to get them chops off some of the red end of the spectrum.

Manufactured articles should be made to be used, not made to be sold!

Fee, Fye, Fow, Fum, A dead man's eye and a parrot's BUM!
