Using FMA, we can analyze the astigmatism and coma in this starting system to gain insight into the nodal aberrations present, as shown in the following figure.

In the case of astigmatism (scale of 1.7 waves), binodal astigmatism is present and in the case of coma (scale of 0.51 waves), the coma is asymmetric. 

To run this analysis in FMA, choose the Analysis > Diagnostics > Field Map menu. In the Field Map dialog box, choose the Wavefront Polynomial coef. performance metric on the Field Display tab.

On the Computation tab, choose the wavefront coefficient numbers you’d like to analyze. These are either the coefficients of the standard Zernike polynomial, or Fringe Zernike polynomial. For instance, choosing the Fringe Zernike polynomial coefficient 9 would analyze the 3rd-order spherical aberration over the field. 

In the case of astigmatism and coma, there are paired terms with an X and a Y component. In FMA, paired terms are coupled by default. Coefficient 5 is coupled with coefficient 6 for astigmatism, and coefficient 7 is coupled with coefficient 8 for coma. When you want to analyze these paired terms, enter one of the coefficient numbers, and FMA knows which terms to couple automatically. 

Taking this analysis of the nodal aberrations a step further, it is possible in CODE V to optimize these freeform surfaces so that the residual aberrations could be corrected by additional rotationally symmetric optics. Using these optimization methods to control astigmatism and coma by constraining their Zernike terms, the astigmatism (scale is 0.87 waves) and coma (scale is 0.66 waves) are:

Current users of CODE V are invited to attend this one-day meeting. The CODE V User Group will be presented in three locations, and as a 3-part webinar series. 

The live meetings start at 9:00 a.m. and end at 4:30 p.m. Complimentary lunch, as well as morning and afternoon refreshments, will be provided.

The following topics are planned for the day. Questions and discussion will be encouraged throughout the day.

• CODE V 11.1 New Features
• Augmented Reality Design with CODE V
• Designing an Automotive Backup Camera with SpecBuilder
• Modeling Diffractive Optics in CODE V
• CODE V Tips and Tricks
• Synopsys Optical Engineering Services: Environmental Analysis and Optimization Case Study
• CODE V Future Plans (Live Meetings Only!)
