Aspheric PLA-Lens (n=1.46) D=50mm f=100mm

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...
