Abstract

Magnetorheological Finishing (MRF) offers an effective way for correcting transmitted wavefront of lenses. Traditional feedback based methods of polishing and testing a lens until it is tolerance made direct correction of transmitted wavefront difficult if not impossible. Being a feedforward, deterministic process, MRF makes direct targeting and correction of transmitted wavefront possible. The lens must have low spherical aberration, and full aperture metrology is required. The metrology will show the sum of all errors, and all errors are corrected simultaneously by fixing deterministically the transmitted wavefront. Optimax Systems uses this MRF process to correct aspheric lenses in transmission to subwavelength errors.
