Silicon Micro Lens Array
We’ve produced a micro lens array using diamond turning (Nanotech 250UPL with 3 axis). The process involved slow speed servo (C-Axis) with a cycle time of 50Hrs (including roughing, semi-finish, and finish). Targeted results are Rq-10nm and surface quality 60-40, we’ve achieved results of Rq-6 to 9nm and surface quality 60-40.
