The chart to the left shows the internal temperature
differences between 0.7m mirror substrates as ambient temperature
falls.
The chart illustrates the substrates cooling during
a 4C/hour drop in ambient temperature. All start at equilibrium
at 20C (upper left of the chart).
The Dream Cellular engineered
substrate stays much closer to ambient temperatures than
even an extremely thin monolithic substrate, including those
made from Zerodur and Astrosital.
These comparisons did not encompass forced ventilation.
The Dream Cellular 0.7m substrate has 4 times the surface area
of the 1.875" thick monolithic, yet the Dream Cellular substrate
is 2 times stiffer than the monolithic. |

Deep blue is the closest to ambient temperature. Note
how the Dream Cellular substrate reaches these blues far sooner
than the monolithic substrates. |
