27/10/2010 · Two lens arrays of 20 lenses (4×5) are fabricated in polystyrene (Rexolite 1422) using a 3-D, three-axis micromilling process. The lenses of one array are concave (Rcurv= –2 mm) and the lenses of the other array are convex (Rcurv= 2 mm). A method for correcting a 3-D micromilling program for a single lens is described and evaluated.
