True Performance Never Fears Change. -It Defies The Status Quo.

**IDream Aerospace Systems was founded by Shane Santi in 2003. He started using optical telescopes in 1980 when he was 10 years old. He's been studying optics and installed performance losses since 1994. He ground and polished his first front surface optical mirror in 2001; a solid, full-thickness mirror. Shane lives in the details & is fascinated by complex systems. This curiosity is driven by a desire to understand what makes things tick. Each time a question is answered, knowledge is gained and the next question is formed. Higher levels of understanding lead to new approaches, new design ideas & new solutions.

Dream Aerospace Systems was founded for three main reasons;
1.) Optimize & combine complimentary technologies - lightweight carbon fiber supports with lightweight optics, while making them accessible to more than just big aerospace/gov't-level budgets,
2.) Solve the century old problem of print-through by engineering better lightweight mirrors and
3.) Deliver higher installed performance optical instruments.

**IOne of Dream's 0.4m instruments outperformed all other optical instruments in a mulit-year NASA program. Other NASA group members were using traditional technology instruments as large as 1m. This validates what G.W. Ritchey showed more than 100 years ago when his 0.5-0.6m optical instruments outperformed 1-1.5m instruments. Ritchey proved that installed performance of the optical system matters far more than aperture size. When competing systems ignore fundamental, centuries old thermal & mechanical performance loss factors, they will never be at the cutting edge. Dream Aerospace Systems is unique in the world because it has pushed installed performance to completely new levels.

**IShane has used his passion and over 30 years of research to create a nearly 100% vertical company that is world-renowned for the unusually high installed performance of its lightweight, low-maintenance optical systems. Even inside an optics lab everything around precision optics affects the installed performance. Understanding these factors allows for greater optimization, which in turn produces higher installed performance. One of Dream's 0.4m lightweight optical instruments achieved 0.8 arc-second raw single image resolution, without using AO, without processing, and from the center of Nazareth, PA 18064; a 6000-person town in the Northeast US, at less than 150m elevation. The atmosphere is not the super-villain we're all taught...

Dream's full opto-mechanical systems achieve superior mechanical and thermal stability by using industry-leading, thin-featured zeroDELTA™ lightweight mirrors. They provide higher resolution & sensitivity, greater throughput, less down time and virtually no maintenance.

By design Dream Aerospace Systems in-house technologies produce athermal instruments.
**IA more mechanically & thermally stable total system can; slew faster, hold optical alignment tolerances, critical whole-field focus & optical surfaces to a higher, more consistent performance level, while that optical system is changing mechanically (instrument angles) & thermally (ambient temperature). These combine to produce instruments that break pyschological norms of what can be expected from a given aperture optical instrument. To believe these improvements have no value is the same argument that critics of G.W. Ritchey made more than 100 years ago. History has proven him correct and his critics nameless.

"We shall look back and see how inefficient, how primitive it was to work with thick, solid mirrors, obsolete mirror-curves, ..."
- George Willis Ritchey 1928 JRASC, Vol. XXII, No. 9, November 1928.
**IDirectly dealing with the source of installed performance losses gives Dream Aerospace Systems athermal instruments exceptional mechanical stiffness & consistency and inherently low maintenance, saving Dream customers tens of thousands of dollars. Dream's optical systems are designed for remote/robotic installations. The extensive use of Dream's CF and CFSC in the mirror mounts, backplates, instrument tubes, mounting plates, lens barrels & lens spacers, etc., are ideal because they have;

****- low mass,
****low CTE (Coefficient of Thermal Expansion) and
****- extreme stiffness.

**IDream Aerospace Systems has unrivaled expertise with its engineered, high-stiffness, athermal carbon fiber structures. These are designed and fabricated in house, then baked in Dream's large oven that controls temperature one full magnitude tighter than aerospace composite ovens. Dream's in-house designed & produced stainless steel threaded inserts have unusually high performance because they are engineered for high stiffness, not just strength. Dream's composites are extremely rugged as well.

Dream leads the world with the truly extensive use of carbon fiber in its opto-mechanical structures.

Dream Aerospace Systems consistently averages 95% or greater carbon fiber and only 5% metals for the weight of the structures in its athermal instruments. (no optics)

**Customers also use Dream's CF & CFSC with zero-expanion mirror materials because they offer higher stiffness, lower mass and more closely match the mirror material than aluminum and steel structures. This can eliminate the need for separate, complex flexures and metering systems, which bring their own risks and performance loss factors to the table. Dream's systems achieve a much higher level of installed performance day after day, year after year, while having the lowest maintenance. What many have considered as performance limits due to atmospheric seeing, is often being driven by poorly finished optics, using traditional mirror technologies and low-stiffness supporting structures; century's old problems that Dream Aerospace Systems has dealt with directly through 20 years of development.

"Hello Shane, I can't think of anyone who has delved as deeply into the mechanics of optical systems as you have."** Dream customer

Dream's carbon fiber is also superb for zero-expansion mirror materials like Astro-Sittal, Clear-Ceram, fused silica, ULE, Zerodur, etc. Click below to see a carbon fiber structure for a 25" Cassegrain that used ULE mirrors.


Connection points are often low-stiffness points. This page shows the pull-out strength of Dream's stainless steel inserts used within Dream CFSC parts.

"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!"
