Abstract (en)
[origin: WO2014158346A1] Embodiments of the present invention relate to apparatus and methods for laser forming of holes in a substrate. In one embodiment, a laser scanning apparatus includes a movable transport assembly, and an optical device disposed adjacent the movable transport assembly, wherein the optical device comprises a polygonal mirror having a plurality of reflecting facets and an axis of rotation, an actuator configured to rotate the polygonal mirror relative to the axis of rotation, and a laser source positioned to direct electromagnetic radiation to at least one of the reflecting facets of the polygonal mirror, wherein the movable transport assembly is configured to position a substrate to receive the electromagnetic radiation reflected from the reflecting facets of the polygonal mirror.
