Interferometer Test of BMC Mirror

• Test giving left half actuators then right half
  100 volts
• Interferometers Isometric plots of mirrors
  surface
• Expected to see half of the surface low and the
  other half high

13
Interferometer Test of Agile Mirror

• Identical Setup just a different mirror
• Left half and right half of actuators given 100
  volts
