Optical alignment optimizes the energy throughput to the detector. Alignment can change
slightly over time, particularly in locations that have large temperature swings or excessive
vibration. After you power up the instrument, allow approximately 6 hours for the instrument
to reach thermal equilibrium before you align it. Repeat alignment every two weeks.
