Paper Abstract

The design of multi-component optical systems can be supported by software tools. Designers are known to change often between different levels of abstraction, sometimes characterizing a lens only by its focal length and at other times giving a full description of the magnetic circuit. A design tool should be able to follow these changes in approach. We illustrate the use of such a tool by describing the design process of an optical system. The example shows the use of different abstraction levels and the program's ability to define constraints such as staying in focus and at a set magnification while optimizing the system's parameters. The optical system which is chosen for the example must image an object to an image plane with variable magnification and variable rotation while obeying certain requirements on resolution and distortion.
