Optical Design Tolerancing
백서
This white paper explores how advanced tolerancing techniques, particularly those available in Keysight's CODE V software, can help engineers strike the optimal balance between design performance and cost-effective manufacturing. It examines traditional approaches like finite difference (FD) and Monte Carlo (MC) methods, detailing their respective strengths and limitations, and introduces CODE V’s proprietary Wavefront Differential tolerancing method.
The Wavefront Differential method combines the sensitivity insight of finite difference with the realistic statistical accuracy of Monte Carlo, all in a dramatically faster workflow. It supports inverse sensitivity analysis, direct tolerance desensitization during optimization, and accommodates realistic compensation strategies, enabling designers to evaluate and refine tolerances throughout the development cycle—not just at the end. Real-world design examples, including a Double Gauss lens and inverted telephoto system, highlight how CODE V’s tolerancing tools can reduce as-built performance variation, streamline production and minimize cost without compromising optical quality.
Learn how CODE V empowers engineers to confidently design high-performance, manufacturable optical systems by leveraging fast, flexible and accurate tolerancing workflows.
