OG exemplary drawing
 
1. A laser marking system for marking a product, the laser marking system comprising:
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, wherein 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;
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; and
an electromagnetic radiation manipulator optically disposed between the first and second optical elements, wherein
a first angle is defined between the first and second rotational axes;
a second angle is defined between the first and second steering axes; and,
the electromagnetic radiation manipulator is configured to introduce a difference between the first angle and the second angle.
