Dream Cellular,
LLC specializes in the design, engineering and in-house production
of cellular substrates and their annealing. All substrates are cast in-house,
typically to +/-1C. This recent 28.5" blank was tested
by Tony Marino of AGI as having 4nm/cm residual stress. |

We do not fuse,
frit bond or use other such processes where individual components
are cut and then assembled. These methods often make it extremely
difficult, if not impossible, to vary specific rib thicknesses,
create tapered ribs, etc. All of Dream Cellular, LLC's
blanks are cast (melted) so as to produce a single, continuous
blank that does not suffer from potential bonding issues the
other processes can experience. We can create designs that are
far more optimized than fusing allows. |

Dream Cellular,
LLC's lightweight optics have no rivals because of the extent
of engineering and intelligent design that is put into every
blank. We bring an extensive knowledge base due to years of design
experience in cellular optics as well as supporting and using
such optics through our sister company, Dream Telescopes & Acc.,
Inc.. In this way
we have closed the design and engineering loop because we do
not simply design and produce cellular blanks, we use them in
full instruments. This broader-based, real-world knowledge allows
us to maximize the blank's design and features in every way.
Designing in features that are unique to optical support are
imperative. Dream Cellular, LLC is creating blanks that are not
just light, stiff and with a much shorter thermal time constant
but functional and optimized to a degree never seen
before. |

Because we produce
the engineered, lightweight mirrors in-house it gives Dream control
over scheduling/delivery, as-designed versus as-cast variance,
annealing and an ability to quickly modify any design.
All of Dream Cellular's
light weight mirror blanks are designed using an iterative design/FEA
process to reach the design goals for both polishing and
gravity displacements. |
