True Performance
Doesn't Fear Change. It Defies The Status Quo.™ |

Dream's carbon fiber & carbon
fiber skinned sandwich core components
and structures for a 25" Cassegrain telescope that uses
solid ULE mirrors. |
 |

|
|
Telescope without optics. One of the two flat mounting
areas for the telescope tube can be seen. These are carbon fiber,
not metal. |
|
Dream's SolidWorks CAD model of the telescope with
the customer's ULE solid mirrors installed. |

Close up of backplate showing custom insert pattern
for customer's requirements. Stainless steel inserts
are made in-house. |
|
4-vane spider assembly with low-profile M2 focus using
wide-footprint stainless steel linear bearings for superior stiffness,
maintaining tighter optical alignment tolerances. Linear actuator
stalls at 95lbs of force & moves at 1.25µm for each
full step. |

Dream is the only
company in the world that uses engineered carbon fiber so extensively
in the structures - averaging 95% carbon
fiber and only 5% metals for the weight of the structures.
Other companies say "carbon
fiber telescope" but they average 5-10% carbon fiber and
90-95% traditional metals, most of that being inexpensive, high
CTE aluminum. Ask questions to understand what it is they're
selling.
Don't accept the excuse that this
level of performance isn't needed. There's a reason Dream is
the only company that publishes raw, all-sky test images taken
on an EQ mount (far more demanding than alt/az tests), showing that Dream's athermal instruments don't need
to adjust focus to "correct" for mechanical & thermal
errors. Dream delivers the highest installed performance in the
world. |

Dream's carbon fiber
is ideal for use with not only Dream's engineered, lightweight
mirrors but is also superb when used with zero-expansion mirror
materials like; Astro-Sittal, Clear-Ceram, fused silica, ULE,
Zerodur, etc. |
