Abstract
method and apparatus for aligning an optical element in an optical sub-assembly is provided. Pivoting fine tuning plates connected to the main body of the sub-assembly are used to set the height and angle of the optical element. The optical element is connected on a pin through the optical element frame between two portions of the main body. Pivoting the fine tuning plate with a cam causes the optical element pin to cant, adjusting the position and/or angle of the optical element. In one embodiment of the present invention, a laser may be used to better align the optical element.
