- 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.

- 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.

- 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,

- 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.
