Spherical Projection System

The Spherical Projection Device uses two first-surface mirrors: a curved mirror and a flat mirror. In the Spherical Projection System, both the curved mirror and the flat mirror compliments each other to project high quality visuals from the HD Projector.

The Projection System is designed to use an HD projector with a resolution of 5000 or more, although higher resolution projectors for portable systems may become available in the future. Brighter projectors usually have superior performance – especially in larger domes. Unlike the fisheye, which must be installed in a specific projector, the Spherical Projection System takes a range of standard HD projectors found in home theaters and conference rooms. In the HD projection over 84% of the projector’s pixels reach the dome with over 95% of the dome covered. When a projector needs repair, a second projector can replace it immediately. It rarely needs repair, but customers may change out the primary convex mirror after several years of use.

It is very portable and normally travels on top of a rolling case containing the projector, laptop and sound system – for easy transport to a school or community setting. An operator with practice can set up a Standard Dome and Spherical Projection System in less than 30 minutes, with similar amount of time required for takedown. The dome, fan, and projection system can all fit on one hand-truck.


1. It is less expensive that fisheye solutions. There is no debating this fact.

2. It eliminates chromatic aberration associated with the horizon of fisheye lenses.

3. Projection solutions are resolution independent with the only limited to the resolution being the projector you have chosen to use.

4. Projection solutions are infinitely upgradable. You are not stuck with the initial projector you have chosen. As projector technology continues to improve in lumens and resolutions, you are free to change out for a new projector while repurposing the original projector for classroom or other uses without penalty. This makes the mirror solutions green and better for the environment.

5. More pixels on the dome! A fisheye lens coupled with a high definition projector loses over 50% of the available pixels due to the round nature of the dome master that the fisheye lens must project. A warped image, designed for a mirror captures 84% of the available pixels giving you more pixels on the dome and higher resolution regardless of what ever projector comparison you choose to make.
