Abstract
An optical sight for a computer controlled plotter includes a magnifying lens positioned in an image path through the sight. The magnifying lens magnifies the image of the reference point located by the sight about an optical axis through the sight. The magnification achieves greater accuracy in locating the reference point. An electronic device which responds to light impinging thereon is positioned in the image path at the optical axis. Position signals supplied by the electronic means are related to the location of the impinging light of the reference point relative to the optical axis. The position signals are used by a computer controlling the plotter to manipulate the plotter to automatically locate the reference point.
