Early 2019

Dream is proud to be chosen for;
 

* An athermal, alignment telescope for the world's highest resolution telescope array.
* A critical fold mirror and dedicated, athermal mirror mount for the world's largest solar telescope.
Both projects use Dream's core technologies; carbon fiber and highly optimized, lightweight mirrors.

December 31st, 2018: Dream successfully produces custom ~250mm, f1.0 perforated zeroDELTA lightweight substrate for aerospace prime.

This is the fastest mirror Dream has produced to date, beating out a ~400mm, 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 glass mirror blanks (20mm to 1.15m), as well as finishing of lightweight optical mirrors. 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.

zeroDELTAaspheres have been finished to L/125 RMS surface, 2Å RMS surface roughness and radii as close as 0.002% of nominal. They can be finished to a super-polish (1Å or less), which is limited by the process & optical metrology, not the zeroDELTAmirror.

Dream also produces athermal carbon fiber mirror mounts & cutting-edge, athermal full optical assemblies & instruments.
 

"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!"
- Ted Kamprath
40 years in professional optics, using everything from million dollar test rooms to 144" Continuous Polishers.

During the coldest weather in at least 25 years, Dream finishes two more zeroDELTA mirrors in its extremely stable polishing & testing room. Click the image to see amazing videos.
 

Dream casts and fully processes a bubble-free f1.376 mirror for an Adaptive Optics project. The mirror is six times lower in areal density than Hubble's M1, but is finished with conventional polishing techniques.


 

 

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

zeroDELTA enables our customers through SWaP-C; Size, Weight & Power, Cost:

* Elimination of quality-robbing boundary-layer mirror seeing,

* Elimination of figure-distortion caused by internal temperature gradients,
making zeroDELTA mirrors process & finish to zero-expansion levels.

* Maintain today's tight optical alignment tolerances through low mass
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 & mechanical performance does not force
the use of expensive finishing techniques and/or technologies.

All of the above benefits at 5-10x lower cost than pocket-milled zero-expansion mirrors.
