    Summary

    Ion beam figuring (IBF) effectively corrects surface errors in nickel phosphorous (NiP) mirrors used in space optics. This noncontact method significantly improves mirror surface quality, achieving sub-5 nm irregularities for critical applications.

    Area of Science:

    • Optical Engineering
    • Materials Science
    • Space Instrumentation

    Background:

    • Nickel phosphorous (NiP) is a key optical material for space-based visible to mid-infrared instruments.
    • Electroless NiP deposition followed by single-point diamond turning (SPDT) is a common fabrication process.
    • SPDT introduces low- and mid-spatial frequency errors, degrading optical performance.

    Purpose of the Study:

    • To demonstrate the efficacy of ion beam figuring (IBF) in correcting surface errors on NiP-coated mirrors.
    • To quantify the improvement in surface quality achieved by IBF for both flat and spherical NiP mirrors.

    Main Methods:

    • Application of ion beam figuring (IBF), a noncontact, deterministic surface correction technique.
    • IBF was applied as a final fabrication step to NiP-coated flat and spherical mirrors.
    • One flat mirror underwent additional chemical and mechanical polishing before IBF.

    Main Results:

    • IBF reduced root mean square (RMS) height error on a flat NiP mirror from 16.3 nm to 3.4 nm over a 25x15 mm² clear aperture.
    • IBF decreased surface irregularity on a spherical NiP mirror from 13.8 nm to 4.4 nm RMS.
    • Diamond turning marks remained as a limitation, but a polished and IBF-treated mirror achieved 1.9 nm RMS irregularity.

    Conclusions:

    • Ion beam figuring is a viable and effective method for correcting low-spatial frequency errors in NiP mirrors.
    • IBF significantly enhances the surface quality of NiP optics for demanding space applications.
    • Combining polishing with IBF offers a pathway to achieve even higher surface precision.
