Alignment

Set Up

1. Ensure that the alignment laser is level with the table by checking its height at two separate, far apart locations on the bench.
2. Ensure that the alignment laser is collimated. Below is a table of wavefront radii of curvature at different distances from the laser as measured with a Shack-Hartmann wavefront sensor.

| Distance, cm | RoC, m | | 50 cm | -30 +/- 1 | | 75 cm | -35 +/- 2 | | 100 cm | -40 +/- 3 |
