An apparatus for processing a work-piece (80) includes a laser source (102) and a first lens assembly (108). The laser source is configured for emitting laser beams. The first lens assembly is configured for adjustably focusing the laser beams onto the work-piece. The first lens assembly is disposed in optical alignment with the laser source and includes a first lens set having a positive refractive power and a second lens set having a negative refractive power. Because of the first lens assembly, the laser beams emitted from the laser source can be focused accurately onto the work-piece, and then the apparatus for processing the work-piece has accurately focused laser beams as a result.
