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 are present in either case.
The stock of 12 mm long lenses is displayed. Other lengths available on request.
