Using Ion Beam Machining to Increase Productivity When Manufacturing High-End Optics

Presentation will begin: Tuesday, January 10, 2023 - 12:40 PM EST
Presented by: Christian Schindler, Buhler

Ion beam figuring has a long history in the manufacture of classical, high-end optical components. Demanding telescopic or lithographic optics have traditionally been enabled through deterministic and highly reproducible focused ion beam machining on various optical materials. The whole process to produce such delicate components as spheres, aspheres, plano optics, and freeforms still relies heavily on the optics craftsman’s experience and patience in mastering the interchange between interferometric testing and the ultraprecise, locally determined material removal. With focused ion beam machining, the lowest figure errors in the P-V of less than lambda/200 and microroughness values of less than RMS = 0.1 nm are achievable by accurately planning iterative processing.

In contrast to historical approaches to production, today's industry and research applications in precision optics and semiconductors demand the same or higher quality — but often in higher quantities and faster production. New process approaches need to be found and descriptions made for higher material removal without compromises in quality. Schindler discusses how to implement productivity into ion beam machining, with the aim of directly shaping aspheres or freeforms and manufacturing higher quantities.
