Set binning to 1x1.

Exposure time to 0.1

SBIG Universal Camera, temperature cooled to -8.2 deg C

Mercury Lamp

Focus

  • Took measurements from 18.50mm to 21.50mm with angle micrometer at 2.6mm, grating micrometer at 4mm. In steps of 0.20mm.
Angle
  • Took measurements, with focus micrometer at 20.20mm, of the micrometer from 0.00mm to 4.00mm in steps of 0.20mm.
Grating
  • To see if there is any difference in spectral line measurement when changing the grating (ie is camera better at the edges)
  • Took measurement from 1.00mm to 12.00mm in swteps of 0.50mm
  • Took closer measurements of the grating from 3.20mm to 4.80mm in steps of 0.10mm.
