Understand The Benefits Of Dream Cellular Optics

The image to the right shows the back of an engineered 0.4m (16") round primary mirror produced in-house at Dream Cellular, LLC. The following page shows some of the extensive FEA that was done on this design prior to casting the first article. 18 separate iterations were run on one of two machines that each have 32Gb of RAM.

Dream Cellular, LLC's engineered substrates achieve much shorter Thermal Time Constants (TTC) compared to even an extremely thin monolithic substrate. The TTC of a 1.2" thick 16" monolithic is 36 times slower than Dream's engineered cellular optic. The TTC of a 2.7" thick 16" (full-thickness) is 178 times slower than Dream's optic.

The 16" is approximately 2.25" deep at the outer edge.

Dream is focused on deliveries. The five 16" engineered cellular blanks to the left were cast in less than eight weeks.

Our engineered cellular substrates can be used both perforated, like a conventional Cassegrain employs, or non-perforated. They can also be produced for anything from flat to fast, deeply curving f-ratios. We customize each blank so the ribs match your ROC, thus making the face an even "thickness" across the entire aperture.

Dream Cellular, LLC can also engineer and produce other shapes, in-house. Click on the image above to see ellipse examples.

Above is a 16" Ritchey-Chretién optical set for one of Dream Cellular's OEM clients. Dream can match the rib geometry with your exact ROC's. This makes the face the same thickness across the entire aperture. Click on either image to see other photos and the custom packing used for optical sets like this.
