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.
