Abstract
A projection system includes a collimating lens group for collimating an imaging beam. The collimating lens group has an optical axis that is de-centered with respect to the axis of the imaging beam. Further, the optical axis of the collimating lens group forms a non-zero angle with the axis of the imaging beam. The de-centered collimating lens group enables the use of more conventional projection optics, without the unacceptable displacement of the projected image.
