655-311 Optical Design and Ophthalmic Metrology

Credit cannot be granted for both this subject and 655-210 prior to 2004.

655-101, 655-102 or 655-202 Optical Systems.

The purpose of this subject is to provide an understanding of the principles and techniques of optical design including an understanding of the control and optimisation of aberrations. It is an introduction to ophthalmic lenses and spectacle lens design. The topics covered include aberration theory, optical design and control of aberrations including the design of ophthalmic lenses, advanced photometry and radiometry, and optics of commonly used ophthalmic instruments. Practical classes will include computer-aided tutorials on both optical design and lens calculations.

A 3-hour written examination at the end of the semester (80%) and assessment of practical work and assignments (20%). A pass must be obtained for both the written and practical work.
