Claim 0:
1. A combined lenses-based apparatus for line laser uniformity generation, comprising: a laser diode (1), and an aspheric focusing lens (2) and combined lenses (3) that are arranged behind the laser diode (1) sequentially, the combined lenses (3) comprising a cylindrical lens (21) and a plano-convex cylindrical lens (22), the cylindrical lens (21) and the plano-convex cylindrical lens (22) being arranged on an optical path sequentially, one end surface of the aspheric focusing lens (2) being an aspheric surface, light emitted by the laser diode (1) being focused in a linewidth direction of line laser and in a linelength direction of line laser by passing though the aspheric focusing lens (2), and the combined lenses (3) dispersing a focused beam in the linelength direction of line laser into uniform line laser.
