Synopsys CODE V 10.3 Optical Design and Analysis Software

Synopsys introduced version 10.3 of their CODE V optical design and analysis software. CODE V is an optical engineering and design software. It is used for the optimization, analysis, and tolerancing of image-forming optical systems and free-space photonic devices. CODE V 10.3 features new aspheric design tools. Aspheric surface shapes are used to help reduce or eliminate imperfect or blurred images in optical systems. An aspheric lens can be used to replace multiple spherical lenses. The CODE V 10.3 is available now.

CODE V 10.3 Features

Support for Q-type Aspheric Surfaces
The tool now supports new native aspheric surfaces based on mathematical formulations recently published by Dr. G.W. Forbes of QED Technologies. These 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 fast wavefront differential tolerancing feature supports tolerancing on Q-type polynomial coefficients, which is useful for evaluating system performance and manufacturability.

Built-in Aspheric Constraints for Design Optimization
The built-in optimization constraints enables designers to directly control the sag or slope variations of Q-type aspheres to maintain manufacturability of the lens system. For example, these constraints give engineers 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.

Asphere Expert Tool
the Asphere Expert tool saves designers time and effort by automatically finding optimal asphere locations in the lens system. The tool uses a unique, highly efficient algorithm that takes into account both aspheric slope departure limits and weighted constraints when computing recommended aspheric surface locations. Developers have the option to convert selected surfaces to aspheres and optimize the resulting system for best final performance.

Enhanced Surface Conversion Capabilities
The enhanced surface conversion makes it easy to switch back and forth between the Q-type formulations and traditional aspheric surface representations. This enables engineers to harness the power of the new formulations while maintaining compatibility with established fabrication processes.
