OptiPro Systems has been a pioneer in the field of optics manufacturing and freeform geometry is no exception. We have improved our existing grinding and polishing platforms to facilitate easier fabrication of optics with complex shapes and difficult materials as well created our own software packages specifically tailored to these processes. In this paper we will discuss some of the challenges associated with complex shapes and some of the techniques and technologies we use to overcome them. We will discuss some of the difficulties associated with the qualification and tolerancing of these freeform prescriptions as well as some possible solutions to reduce manufacturing costs while still fabricating effective parts. Examples these difficult shapes will be provided alongside of results and data from processing.
