• Camera Setup
  • camera temp = 5 deg
  • Focus distance = 19.9mm
  • Camera Angle = 4.6mm
• Low Mercury
  • Exposure 0.2s
  • Micrometer position 0-12mm in 0.5mm intervals
  • Changed exposure to 0.3s
  • Towards edges of the frames, the spectral lines appeared to be a little out of focus in comparison to the centre.
• Helium
  • Exposure = 0.3s
  • Micrometer position 0-12mm at 0.5mm intervals
• High Mercury
  • Exposure = 0.001s (small as possible)
  • Increased distance of lamp from optical fibre as images satuated
  • Some lines still saturated
  • Micrometer position 0-12mm at 0.5mm intervals
• Cadmium
  • Exposure = 0.5s
  • frames taken at 0.5mm intervals between 0 and 12mm.
