Dream specializes in the
optimized design, engineering and in-house production of its
bubble-free zeroDELTA™ -lightweight mirror blanks, as well
as finishing of lightweight optical
mirrors & sets.
Dream's level of engineering,
innovation and process control offers our customers the latest
in modern, unparalleled performance, including low MSF and low surface roughness.

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

zeroDELTA™ enables our customers
through
SWaP; Size, Weight
& Performance: |
|
* Elimination of quality-robbing boundary-layer
mirror
seeing,
which is a centuries old problem with solid mirrors. |
|
* Elimination of figure-distortion caused
by internal temperature gradients, making zeroDELTA™ mirrors process
& finish
to the same
levels
as zero-expansion mirrors. |
|
* Maintain tight optical alignment tolerances that come with today's
latest optical designs - Dream's mirrors are 1/3 to 1/6 the mass
of solid mirrors. |
|
* Faster slews,
better tracking performance and higher throughput due to lower
inertia of the total instrument. |
|
* Dream's level of engineering and therefore
the mechanical
performance
of the mirrors does
not force
the use of expensive finishing techniques and/or technologies. |
|
* All of the
above at 6-10x lower cost than pocket-milled zero-expansion mirrors. |

This hyperboloidal convex secondary mirror (M2) was
part of a Dream 24" Ritchey-Chrétien telescope for
a NASA project. |
