ABSTRACT:
A high aperture finite conjugate lens suitable for use in applications requiring high numerical aperture on both object and image sides of the lens such as in a laser thermal printer system. The lens system has six lens components, the first lens component is identical to the sixth lens component but is reversed in orientation; and the third lens component is identical to the fourth lens component, but is reversed in orientation.
