December 31st, 2018: Dream successfully produces custom f1.0 perforated
zeroDELTA™ lightweight substrate
for aerospace prime. |
 |
|
|
|
|
This is the fastest mirror Dream
has produced to date, beating out a f1.376 Dream designed and
fully finished in-house in 2016. |

Dream specializes in the
optimized design, engineering and in-house production of its
disruptive technology bubble-free zeroDELTA™ -lightweight
mirror blanks (25mm to 1.1m), as well as finishing of lightweight optical
mirrors & sets. Dream's level of engineering,
innovation and process control offers our customers an enabling
technology with unparalleled performance, including low MSF and low
surface roughness.
Dream also
produces athermal carbon fiber mirror mounts & cutting-edge
athermal full
optical assemblies. |

"Your company
does phenomenal work. There is a lot of thought and heart that
goes into your products. Dream's engineering sets their lightweight
mirrors apart from competitors. Your engineering goes beyond
the lightweight aspect. You focus on actual performance!" |

zeroDELTA™ enables our customers
through
SWaP-C; Size, Weight
& Power, Cost: |
|
|
|
* Elimination of figure-distortion caused
by internal temperature gradients, |
|
|
* Maintain today's tight optical alignment
tolerances through Dream's |
|
mirrors being
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. |
|
|
the use of
expensive finishing techniques and/or technologies. |
|
|
All of the
above at 6-10x lower cost than pocket-milled zero-expansion mirrors. |
