# Photonium

> Photonium pairs senior optical engineers with AI-driven automation that takes optical designs from spec to toleranced export. It drives the tools teams already use — Zemax, CODE V, or an in-house optimizer — rather than replacing them.

## What Photonium offers
- Photonium Insight (software): automates the optical design loop — Start → Run → Evaluate → Diagnose → Iterate → Package. Proposed design changes are applied only after engineer approval.
- Custom automation: built around a team's exact optical workflow (RFQ feasibility, design setup, optimization, tolerancing, factory handoff).
- Consulting: senior optical engineers across semiconductor, aerospace & defence, automotive, life sciences, and consumer electronics.

## Key facts
- Tool-agnostic: works with Zemax, CODE V, or an in-house optimization engine; native .ZMX import and export.
- Engineer-in-the-loop: the AI drives existing tools and proposes changes; engineers approve before anything is applied.
- Backed by Y Combinator.
