Optical Quality
•We have demonstrated a
lot of control over optical aberrations:
–Radial coma: re-space
body 4/ element 9
–Lateral coma: moving
body 4 in x & y
–Focus: move body 4
axially (effect on radial coma not yet
investigated)
–Focus: presently not far enough back of dewar window, but collimator can be moved forward to cure this.
