Dream specializes in the optimized design, engineering and in-house production of bubble-free lightweight mirror blanks, as well as finishing of lightweight optical mirrors and optical sets.

Dream's level of engineering, innovation and process control offers our customers unparalleled performance, including low MSF errors.

Dream's lightweight optical mirrors offer:
* Elimination of quality-robbing mirror seeing, which is a centuries old problem with solid mirrors.
* Maintain tighter optical alignment tolerances that are a must for modern optical designs. This produces higher system performance because 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.
* Less down time because their lower mass means faster removal and re-installation after recoating.

A smart phone upgrades every three months. Solid glass mirror technology has changed little over the last 166 years.

If you missed seeing a Dream engineered lightweight mirror in person at SPIE DCS trade show in Anaheim, CA in mid April, here are your next opportunities:
- August 8-10, SPIE Optics and Photonics, booth 8548
- September 19-20, OSA Frontiers in Optics, booth 314
- October 17-19, SPIE Optifab, booth 212

"We shall look back and see how inefficient, how primitive it was to work with thick, solid mirrors, obsolete mirror-curves, ..."

Dream mirror finished to higher quality level than Hubble Space Telescope's M2

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

Dream delivers a fast & demanding 300mm CA f3 Ritchey-Chrétien optical set.

Dream directly 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.
