Abstract
A method for example of irradiating a light-curable material, may comprise irradiating light about a first axis from an array of light-emitting elements towards a light-curable surface, directing the irradiated light through an optical element interposed between the array of light-emitting elements and the light-curable surface, wherein a central axis of the optical element is offset from the first axis, and deflecting the irradiated light directed through the optical element asymmetrically away from the first axis towards the light-curable surface.
