technology is also incorporated on the secondary support to reduce vibrations to
telescope structure.
-Secondary Support Vanes: Ultra-thin steel 10mm/.39inch thick to reduce infrared
background "noise"
- Tip-Tilt Frequency: limited to structure resonance frequency - approximately 20 Hertz
(closed loop bandwidth)
- XY & Focus Positioning Precision: Approximately 2 microns
