Paper Abstract

Synopsys OSG ( formerly Optical Research Associates ) have recently developed a CODE V® feature called 'Glass Expert'. Taking advantage of modern computing power, this program extends the normal optimisation methods by allowing a large number of glass types to be substituted into a lens system in an automatic way . We evaluated this software, applying it to a small number of suitable lens systems . We wanted to discover how quickly it runs, how the user input choice affects the end-result , and at what point of the design process it is most valuable . The exercise proved to be very interesting. We describe how, in one case of a highly colour-corrected visible system, the macro was able to reproduce, within a couple of hours , most of the glass choices I discovered over a period of a couple of weeks in the original design process. While this macro is obviously useful for specially-corrected visible systems, it is also potentially useful for mid-wave IR and the important short-wave IR ( SWIR ) band. An example of re-optimisation of a NIR/SWIR –band lens is given . ‘Glass Expert’ also offers the interesting possibility of swapping air and glass materials in an automatic way. We tried this option on one example, but ran into some problems that require further thinking . Some other pitfalls, and potential future improvements in the software are mentioned. We also describe how ‘Glass Expert’ and Global Synthesis® can work very effectively in combination .
