Jeffrey and Melissa Pilgrim launched Vista Photonics in 2003 to research how laser-based trace-gas sensors could be developed for a variety of commercial and project-specific uses.
Among other innovations, the company created an instrument that helps farmers plan harvests by measuring how much ethylene gas crops emit to accelerate ripening. But the couple’s favorite brainchild so far is the optical life gas analyzer they developed for the National Aeronautic and Space Administration. The device monitors gas levels on the International Space Station — a function that’s critical to maintaining a balance of oxygen, carbon dioxide, water vapor and ammonia in the craft’s controlled atmosphere.
