Set Up

The distance from the center of the OTR target (also the center of the 6-way cross) to the closest position we place our first lenses is 13 cm.

Edge to edge OTR cone diameter size ([math]\displaystyle{ 4\theta }[/math] angle,[math]\displaystyle{ \theta=\frac{1}{\gamma} = }[/math] ) at this distance is 2.665 cm.
