Claim 0:
1. An ophthalmic laser system comprising:
a laser engine capable of generating a femtosecond laser beam;
a laser delivery system comprising:
a laser beam shaper module that shapes the generated femtosecond laser beam to generate a shaped laser beam; and
a laser guide having a scanning module, a focus module, and an objective module,
wherein the scanning module has a first lens at a receiving end and a second lens at a transmitting end, wherein the second lens is a plano-convex lens and the receiving end receives the shaped laser beam and brings the shaped laser beam into focus thereby creating a focused beam that is transmitted from the transmitting end into the focus module,
wherein the focus module receives the focused beam from the scanning module and revert the focused beam into a parallel light stream and further directs the parallel light stream into the objective module, the focus module having a first lens and a second lens, wherein the first lens is a meniscus lens and the second lens is a plano-convex lens,
wherein the objective module directs the parallel light stream from an input end thereof to an output end and into a focal point within a three dimensional target space to enable eye surgery of the human anterior segment, and the objective module comprises a plurality of lenses having no less than four lenses, and no more than five lenses, of which three lenses are plano convex lenses.
