17 September 2008 Diamond micro-milling for array mastering
Author Affiliations +
We will present recent advances in Kaleido Technology on the ultra-precision diamond-milling process, which is an extremely versatile tool for manufacturing of masters for wafer-based replication technologies. Diamond-milling has the advantage of being able to manufacture lenses with much larger radii of curvatures compared to etching methods. Spherical-, aspherical- and free-form-surfaces have been machined with form accuracies better than 200 nm (PV), arrays up to 50 x 50 mm have been manufactured on wafers, with lens-position accuracies better than 3 μm absolute over the entire wafer.
