About this 3D model

This is an aspheric lens to be printed of PLA with refractiv index of 1.46. the focal length is 100mm and the diameter is 50mm The numerical aperture is something about 0.22. I optimized it for minimum wavefront error. coefficients for asphere equation: r = 49.150645 conic = -0.658584 A_4 = 8.873082E-008 A_6 = 6.821930E-012 if you are able to print if with a surface quality better than lambda/5 it should be limeted by diffraction ;) have phun...
