Abstract:
A laser diode collimating and aberration correction molded plastic optical system comprising:an emitter that propagates a beam having a first axis perpendicular to the direction of propagation and a second axis orthogonal to said first axis; a first cylindrical lens optic for collimating said beam along said first axis; a diffractive surface for collimation of said beam along said first axis and said second axis; and a second cylindrical lens optic for collimating said beam along said second axis; wherein each of said first cylindrical lens optic, said diffractive surface and second cylindrical lens optic are molded in plastic and include an alignment aid, and wherein said alignment aids mechanically couple the first cylindrical lens optic, the diffractive surface, and the second cylindrical lens optic into an alignment with respect to said first axis and said second axis.
