Spherical surfaces for precision optical instruments have long been preferred over aspheric surfaces due to ease of manufacture. Aspheric surfaces have been far more difficult to manufacture despite known advantages in system performance, size, and weight. Lack of generic testing methods, and non-deterministic nature of optical polishing process are still the main hurdles to cost-effective aspheric surfaces. However, recent developments in testing and manufacturing techniques are gradually stimulating the use of aspherics. The thesis starts with a historical review of optical manufacturing methods. The main body of the thesis explores theoretical and experimental work towards efficient polishing of aspheric surfaces. Firstly, material removal experiments using a sub-diameter pitch tool under active control are described, investigating the relationship between the removal rate and mechanical polishing parameters. Secondly, the characteristics of spinning compliant tools for rapid aspheric production are investigated, and the feasibility of using the spinning compliant tool for efficient aspheric polishing is assessed. Thirdly, a numerical index representing the manufacturing difficulty for aspheric is reviewed and further developed. The thesis concludes with an overview of the prospects for the manufacture and use of aspherics in the future, together with the research required to make this a reality.
