Dream Telescopes & Acc., Inc. is proud to be the
first company in history to have offered a standard product line
that includes such extensive use of Carbon Fiber skinned Sandwich
Core (CFSC) in combination with Dream
Cellular, LLC cellular
mirrors. Both technologies are designed, engineered and produced
in-house. Years of developing and in-field testing of complete
systems have culminated in a very unique opto-mechanical capability
and expertise. Our expertise lies not only in advanced composites
and cellular optics but also in supporting the optics and using
the ultra-high stiffness, low mass and low CTE that our specific
CFSC matrix can bring to an opto-mechanical instrument. Dream's
products are far more efficient than decade and even centuries-old
technologies.
Although we will consider custom, finished instruments,
we are shifting focus from the finished standard product line
to helping other opto-mechanical companies use CF and CFSC products
to a much greater degree. As well as focus on helping customers
obtain higher performance through the use of Dream
Cellular's engineered cellular mirrors. |
