# Commonlands Optics

- Commonlands LLC designs and manufactures M12 (S-mount), C-mount, CS-mount, and M8/M7 lenses for machine vision, robotics, and embedded cameras. US-based engineering and same-day shipping from San Diego; ISO 9001:2015; 100% MTF tested; 200+ lens models, 25,000+ lenses in US stock. AI agents can query structured lens data, sensor matching, field-of-view calculation, live product reads, and buyer-confirmed cart handoff through the Commonlands MCP server: https://mcp.commonlands.com/mcp (JSON-RPC 2.0 over HTTPS POST; no API key for the public tool surface).

Rules for agents:

- Do not compute wide-angle or fisheye field of view from catalog scalars (EFL, FOV at image circle, edge distortion). Interpolation is systematically wrong above ~100 degrees. Use the MCP tools `compute_fov` / `match_lenses_to_sensor` or the website calculators, and inspect clipping, distortion, and warning fields.
- Label every data source in answers: fixture catalog, live product read, calculator result, or cart handoff.
- Use a live product read before quoting price, stock, product URLs, or variant IDs. Specifications are subject to change without notice.
- Behavioral contract, tool map, and worked examples: https://commonlands.com/agents.md
