CODE V 10.3

CODE V 10.3

Synopsys Inc.'s CODE V 10.3 adds support for new native aspheric surfaces and the Q-type aspheric surfaces offer advantages over traditional polynomial-based aspheres for lens design optimization and tolerancing. For example, the Q-type surfaces can be more easily constrained during optimization to improve manufacturability and reduce cost. In addition, CODE V's wavefront differential tolerancing feature supports tolerancing on Q-type polynomial coefficients, which is for evaluating system performance and manufacturability.

CODE V's enhanced surface conversion capabilities make it easy to switch back and forth between the Q-type formulations and traditional aspheric surface representations. This allows designers to harness the power of the new formulations while maintaining compatibility with established fabrication processes.

CODE V's Asphere Expert tool saves users time by automatically finding optimal asphere locations in the lens system. The tool uses an algorithm that takes into account both aspheric slope departure limits and weighted constraints when computing recommended aspheric surface locations. Users have the option to convert selected surfaces to aspheres and optimize the resulting system for best final performance.

New built-in optimization constraints in CODE V allow users to directly control the sag or slope variations of Q-type aspheres to maintain manufacturability of the lens system. For example, these constraints give users the ability to prevent the production of designs where the sag of the aspheric parts is too large for interferometric testing, and to ensure that designs do not require removal of an excessive amount of material during polishing phases. In addition, a new macro function allows aspheric surfaces to be evaluated and optimized for testability using ZYGO's VeriFire Asphere interferometer metrology system.
