A laser diode collimating system comprises a collimating lens for receiving
a laser beam from a laser diode LD. First and second orthogonally arranged
cylindrical lenses are provided through which the laser beam passes. The
cylindrical lenses are positioned so as to have a substantially common
focal plane and operate substantially independently on the divergence
and/or convergence of the laser beam in its fast axis and slow axis
directions respectively. A convex lens, through which the beam passes, has
a focus lying in the said common focal plane.
