Abstract
A multi-faceted optical device for use in a laser scanner wherein the optical device is rotated about a central axis for rotational movement through a repetitive cycle to reflect and sweep a laser beam through a desired optical space comprises a body member formed by thermoplastic injection molding and shaped to be rotated about a central axis and to define multiple mirror receiving faces. Mirrors are shaped to be received upon the mirror receiving faces of the body member with three raised pads being formed on each of the mirror receiving faces for locating the corresponding mirrors received thereon in a defined orientation relative to the central axis. A fast setting, preferably ultraviolet curable adhesive, is applied to the three pads and the mirrors are forced against the pads and preferably released prior to curing the adhesive by means of the application of ultraviolet light or otherwise to form the optical device.
