xmpl3d14, 14th 'example' data file for CPO3D
Miniature lens for microelectronic switching.
A micro-lens, formed by lithography (and hence imperfect), for micoswitching.
The data were obtained when the memory and speed of PC's was much more limited than at present, so the available number of segments was small and the requested inaccuracies were fairly high to give a quick demonstration.
For a representative 3-dimensional view of the lens, choose '3D display' at the interactive stage, and translate along the x axis by -3.0 and rotate about the x axis by 20 degrees.
