Data Taking with Other Lamps

  • Swapped the Cadmium lamp for Low Mercury lamp.
  • Low mercury - exposure time 0.2s, took 25 frames starting at 0mm to 12mm, focus distance 19.9mm, camera angle 4.6mm.
  • Towards edges of the frames, the spectral lines appeared to be a little out of focus in comparison to the centre.
  • Repeated process: took 25 frames from 0mm to 12mm, changed exposure time to 0.3s, focus and camera angle same.
  • Swapped to Helium lamp.
  • Helium - took 25 frames from 0mm to 12mm, exposure time 0.3, focus and camera angle same.
  • Swapped to high mercury lamp.
  • High mercury - took 25 frames from 0mm to 12mm,
