measured closed loop control to be performing as expected (±0.001") thru 330° rotation
Shack-Hartmann Guide Camera
replaced drive gear spring pin
applied loctite as necessary
measured elastic flexure in barrels ±0.0025" thru 330° rotation (Clamped the motion stage tightly, then dial gauges on the camera barrels; the radial motion stage moved this much.)
measured closed loop control to be performing as expected (±0.001") thru 330° rotation
measured repeatablilty of barrel change to ±0.0005" (within accuracy of dial indicator) thru 330° rotation
