Abstract
A light pen sighting device for aligning the receptor of a light pen with an interactive display includes a support member in the form of a transparent plastic body having opposed parallel surfaces with a reticle in the form of points formed in the respective surfaces and a reflector disposed directly between and aligned with the reticle for reflecting light travelling along the axis of the reticle directly into the receptor of a light pen to which the device is mounted, thereby providing a parallex free light pen. An alternate embodiment utilizes fiber-optics for receiving and transmitting light to the receptor.
