Abstract
An anamorphic optical element and an adjustment mechanism for selectively rotating the optical element either around an axis substantially in a vertical direction, an axis substantially in an optical axis direction, an axis substantially in a plane formed by the vertical direction and the optical axis direction, or combination of axes thereof is used to vary a vertical separation between two or more spots.

1-15. (canceled)
A method comprising:
- forming at least two spots;
- obtaining a vertical separation between the at least two spots;
- comparing the vertical separation to a desired swath height value of a vertical separation to form an error value;
- and
- selectively rotating either a first optical element, or a second optical element, or combinations thereof, around either an axis substantially in a vertical direction, an axis substantially in an optical axis direction, or an axis substantially in a plane formed by the vertical direction and the optical axis direction, or combinations of axes thereof in response to the error value.
