Dream spent three months going through design iterations
and Finite Element Analysis (FEA) for this first generation 16"
lightweight mirror. |

To the right is the FEA of this engineered cellular
primary mirror for polishing. |

The maximum displacement is 7.08nm, which is 0.01287
P-V (1/78th wave at 550nm) at the surface. RMS is 5.06nm, which
is 0.00920 P-V (1/109th wave) at the surface. |

Dream Cellular, LLC models and evaluates their engineered
lightweight mirror blanks for both polishing displacements (movements
that occur while the optician is working it) and for gravity
displacements (what it will do in the telescope/actual use). |
