Leading-edge cellular technology


The cellular blank to the right is 122mm/4.8" in diameter and weighs 133 grams. When polished out it weighs just 120 grams. This is lighter than carbon fiber mirror technology but does not have the surface difficulties that carbon fiber mirrors have seen in the last few decades.

Lightweight mirrors of this nature open up enormous possiblities. They also cool and follow ambient temperatures far more efficiently than monolithic mirrors that weigh roughly four times more. The (back) surface area alone is an enormous advantage, even without considering that it is four times lighter.


This blank is approximately 20mm smaller in diameter than the required secondary for the 32" Danish Project.

The 145mm physical OD secondary for the 32" telescope would weigh approximately 264 grams.
