Electromagnetic Lens Aberration Functions

thingiverse

Models of functions used to correct lens aberrations made for LBNL's NCEM lab. Shapes were originally generated as zero-thickness surfaces in MATLAB and then thickened for printing and exported using Blender. Models can be tricky to print, but the end result is entirely worth it. Support is recommended for all but the "bowl-shaped" models. I had an easier time printing these on SLA machines than FFF/FDM, but both are possible. Wrote a brief article about the whole process, which can be found here: http://blog.madesolid.com/2014/03/printed-mathematical-function/ Yay Math! Yay Science! Instructions Printing on SLA Machines is fairly easy. Provide enough support and print large enough and the models should be fine. Printing on FFF/FDM can be a bit trickier, but a well-tuned machine using support that is not overly dense on the models that are not bowl shaped (so that it can be removed easily enough) will yield best results. Happy Printing!
