ABSTRACT:
An all-reflective optical system uses a mirror with a hole to transmit a focused laser beam to an on-axis elliptical mirror. The reflected beam from the ellipse is predominately reflected off the mirror with a hole and focused to a distant adjustable focus. This focus spot can be positioned by X-Y scanning mirrors.
