Plano-convex acylindric lenses are cylindrical lenses with one surface having aspheric coefficients. These lenses are optimized for infinite conjugates configurations, and are generally used for collimation of laser diode fast-axis.

When full angle fast axis beam divergence of laser diode exceeds 60 degrees, the best collimating lens type is high refractive index acylindrical plano-convex lens. The applications of those microlenses might call for shorter or longer working distance but no side lobes in either case.
