We are excited to announce the development of the new Environmental Analysis Group designed to comprehensively study the performance of optical systems under operational and environmental conditions.

This group will cover the effects of these conditions on image quality, polarization, and other key variables, while a suite will integrate all analyses to provide a holistic view of system behavior. Long-term performance studies will also allow prediction of when a system may reach its operational limits, such as minimum MTF thresholds. This initiative aims to provide engineers with robust tools to understand, anticipate, and optimize optical performance over time.

Want early access? Join our pilot program and be among the first to explore these advanced analysis capabilities!

This example video demonstrates our modular tool architecture, using a Retardance Analysis workflow as a practical case study.

Discover how Zemax’s extension framework enables powerful customization and automation beyond standard features.

In this free one-hour webinar, you’ll learn what’s possible with extensions — from advanced analysis and batch processing to AI-assisted optimization — through live demonstrations of real YKP Optics tools developed for Zemax.

This session is designed specifically for Zemax users who want to explore the next level of optical design flexibility, efficiency, and innovation.

AI-BOLD: AI-Based Optimization in Lens Design

At YKP Optics, we’re building AI-Based Optimization in Lens Design (AI-BOLD), a next-generation optical design engine that works across tools like Zemax and CODE V.

No iterations. Simply input your specs, and the AI-based engine delivers the best possible optical design.

This approach cuts down weeks of manual iteration, freeing lens designers to focus on innovation instead of trial-and-error. We are starting with Zemax and CODE V, but our roadmap expands to all major optical tools, paving the way for the first truly cross-platform lens design engine.

We are currently seeking strategic partners and financial supporters to accelerate development. By joining us today, you can directly shape the future of optical engineering.
