    • Materials Science

    Background:

    • Precision optics manufacturing requires advanced techniques for achieving desired surface figures.
    • Traditional polishing methods can be time-consuming and may lack predictive capabilities.

    Purpose of the Study:

    • To demonstrate the efficiency of a computer-controlled polisher (CCP) process.
    • To evaluate a predictive algorithm for surface figure correction in mirror polishing.

    Main Methods:

    • Developed a computer algorithm to predict surface figure progress during polishing.
    • Utilized the CCP to polish a 1.8-m diameter lightweight glass mirror over four cycles.
    • Compared actual figure improvement against algorithm predictions.

    • The CCP process reduced the mirror's surface figure error from 0.16 to 0.04 root-mean-square (rms) waves (1 wave = 0.633 microm).
    • The polishing activity was completed within 72 hours.
    • Observed a lag in figure improvement compared to predictions, attributed to metrology uncertainty.

    Conclusions:

    • The CCP system demonstrates rapid error correction capabilities.
    • The CCP is a valuable tool for efficient manufacturing of precision optical components.
    • Further refinement of metrology integration can enhance predictive accuracy.
