Abstract

A laser marking system for marking a product includes a marking head having an electromagnetic radiation steering mechanism configured to steer electromagnetic radiation to address a specific location within a two-dimensional field of view. The electromagnetic radiation steering mechanism comprises a first optical element having an associated first actuator configured to rotate the first optical element about a first rotational axis to change a first coordinate of a first steering axis in the two-dimensional field of view and a second optical element having an associated second actuator configured to rotate the second optical element about a second rotational axis to change a second coordinate of a second steering axis in the two-dimensional field of view. The electromagnetic radiation steering mechanism comprises an electromagnetic radiation manipulator configured to introduce a difference between a first angle and a second angle (defined between the first and second rotational and steering (respectively) axes).
