FAQ

No, the mirror system is generally not required and adds significant complexity. It was a solution designed to work around the specific operational constraints of our original facility.

For a new build, we would recommend a simpler and more robust setup: a dedicated projector bolted to the floor and tilted to align with the screen. This removes the need for mirrors entirely, which is a much cleaner approach, if your budget allows.

The specific size depends on your final setup geometry. The most important requirement is that the mirror is thick enough (or mounted to a rigid backing) so that it does not sag or deform under its own weight, which would distort the image.

For reference, the two mirrors we used were 12 inches by 9 inches, with a thickness of 1/4 inch (6mm).

The single most important feature to look for is that the mirrors are "front-surfaced" (also called "first-surface"). This means the reflective coating (typically a thin layer of non-magnetic metal like Aluminum) is on the top surface of the glass, which prevents the double reflection that occurs with standard mirrors.

You can find suppliers by searching online for "front-surface mirrors." We used mirrors from the Two Way Mirrors.

The acrylic pieces are glued together using an acrylic solvent cement, such as Sci-Grip #3 or Weld-On #3.
