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
