Dream's zeroDELTA™ .mirrors and CF & CFSC™ structures are enabling the future of modern ground, air and space with superb next generation price to performance.
 

 

More than 80% of the products that Dream produces are custom. Optimizing advanced structures and leading-edge optical solutions specific to customer's requirements is our norm. 100% of our products are made in the US.

Dream designs, engineers and produces carbon fiber parts and finished assemblies, as well as bubble-free cast glass engineered lightweight precision optical mirrors; from 20mm to over 1m. The interior of our largest composite oven is 3.66m wide, 1.83m deep and 1.68m tall. Both of Dream's core technologies are produced in-house in Nazareth, Pennsylvania (USA). ABE airport is less than 15 minutes from Dream.


zeroDELTAaspheres have been finished to L/125 (5nm) RMS surface, 2Å (0.2nm) RMS surface roughness, with radii as tight as 0.002% of nominal. They can be finished to a super-polish (1Å (0.1nm) or less), which is limited by the process & optical metrology, not the zeroDELTAmirrors.

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

Carbon Fiber Structures:
- Design, Engineering (FEM/FEA) and In-House Production since 2003
- Specializing in Low-Void Carbon Fiber, especially Dream's CFSC (Carbon Fiber skinned Sandwich Core) Parts, Sub-Assemblies & Main Structures
- From Small To Large Parts: Dream's largest composite oven 6' x 12' x 6'
- Vacuum-Bagged & Oven-Baked Parts Using High-Temperture Epoxy
- 95% Carbon Fiber Optical Assemblies By Weight Of The Structures (no optics), Stainless Steel Hardware & Dream's Stainless Steel Inserts For The Greatest Performance & Longevity

Dream's CF and CFSC performance is unusually high because our engineered advanced composite structures have been created from the ground up specifically for demanding opto-mechanical systems, not open-market composites.

Dream's zeroDELTA lightweight mirrors have both unrivaled engineering and performance because we put just as much engineering in the lightweight mirror as the mirror mount. Dream is also at the cutting edge due to the thin features of the zeroDELTA lightweight mirrors.
It takes far more than a good foundation (mirror substrate) to achieve real-world performance;
"It's impossible to talk about actual performance of systems and of individual optics without addressing how humans are influencing that data." Shane Santi - Dream's founder

"Your company does phenomenal work. Dream's engineering sets their lightweight mirrors apart from competitors. Your engineering goes beyond the lightweight aspect. You focus on actual performance!"

Dream's technologies create enabling & disruptive high performance systems by using truly modern materials, techniques and designs that have fully addressed centuries old mechanical and thermal issues in optical systems. Although Dream offers standard optical systems, the bulk of Dream's work is focused on creating custom solutions for clients. Dream can design, analyze and produce a wide range of optical systems, from numerous forms of Cassegrains to corrected Newtonians to wide field 1m prime focus instrument. Our lead optical engineer has nearly 40 years of both design and implementation experience, especially with fast & demanding optical systems.

Finished instruments have the lowest possible maintenance due to Dream's unique technologies. Dream's telescopes are low in total mass, have an extremely low CTE, are corrosion resistant and have a higher stiffness (and strength) to weight ratio than conventional materials. They are designed from the ground up for remote/robotic use. Because of their near zero maintenance they are ideal for border survelience, military, science, education and numerous additional applications.


Dream works in the UV, visual, NIR, Mid to Far IR. Used for; lasercom, LiDAR, AO, atmospheric research, surveys, discoveries, airborne, balloon-borne, optical systems used in dynamic & demanding thermal environments, etc.

Customers using Dream's technologies: US Air Force, NASA, Raytheon, Honeywell, numerous government R&D labs, Universities, Professionals, as well as numerous OEM's, for world-wide customers. Dream is currently registered with DOD & DOE customers, as well as sam.gov.
