Media:champ_triplet_2d_FINAL_v2.dwg: Final dimensions for CHAMP triplet


Prescription:

From 300K->77K, assuming Al contracts by 0.38% (when cooling from 300K->77K):

      CaF2 contracts by 0.284%
      SiO4 expands   by 0.001% [hardly at all]

distances in mm Space between centers of (77K) (300K) Pupil - Lens 1 0.50 0.502 Lens 1 -2 1.805 1.812 Lens 2 -3 5.048 5.067 Lens 3 - IMAGE 42.367 42.528

and also the ACTUAL measurements from ISP.
