New Star Tracker Lens

posted Jul 9, 2015, 8:33 AM by Doug Sinclair
The ST-16RT star tracker has received an incremental upgrade in the form of a new lens.  Our optical designer has done a wonderful job on this, and given us a lens that is:
  • 3.5 mm shorter
  • 5% better photometric efficiency on-axis
  • Wider unvignetted field
  • Even lower chromatic aberration
Star trackers with this new lens, called ST-16RT2, are form, fit and function compatible with the older ST-16RT.  The first flight units will ship in Q3 2015.
