WebOct 31, 2008 · Using the optical method, the lens is mounted on a mandrel, or spindle, and light is passed up through the optic to the operator’s eye (a lit target can also be used). As the mandrel and optic rotate, the collimated beam will appear to move unless the optic is centered. The operator will move the optic while looking at the beam until there is no
