Automatic Design Search Tools in Optical Design
“Traditional (design) methods have long relied on having a good starting point, a design not too far from the desired goals, and then work to improve it… However, one rarely has such a starting point. The core problem here is the fact that, except in a few simple cases, there is no closed-form solution to the lens design problem. That means there is no formula where you can simply plug numbers into and obtain a great design. You have to think, try things, learn from experience, and iterate. My goal in writing the [SYNOPSYS™] program has been to put as much of the burden on the computer as possible...” -- Don Dilworth, Creator of the SYNOPSYS™ Lens Design Software.
The Automatic Design Tools in SYNOPSYS™ are created to provide an effective solution by putting as much of the design burden on the computer, freeing Engineers from the most tedious of the traditional tasks. It aims to ease the process in finding good starting points, and to facilitate exploration of the design space to discover alternative design forms which may deliver better performances not normally realized using conventional design protocols.
In this presentation, we will illustrate the use of the following Design Tools:
- Design Search (DSEARCH): A search tool for fixed focus systems.
- Automatic Element Scanning Tools: These tools scan the lens systems to find the best place to insert or delete elements or to use an unusual surface such as aspheric.
We start with an introduction to SYNOPSYS™ and its automatic design search tools. We will use a seven- element system as an example to illustrate the DSEARCH tool in SYNOPSYS and how the system tolerance requirements can be relaxed when searched with the tolerance desensitization goal. Then we will show how to use the automatic element insertion/deletion tools to improve the lens system.
