Abstract
Several aspheric lens elements have recently been produced using new manufacturing processes. Deterministic microgrinding and magnetorheological finishing technologies were employed to fabricate ten 47 mm diameter plano convex hyperboloidal aspheric condenser lenses. The parts had an aspheric departure of 145 microns from best fit sphere, with a final figure requirement of approximately one micron p-v. The lens elements were tested at the component and systems level and passed all end user requirements.
