RefFIT

Introducing the RefFIT web application: a powerful and user-friendly tool for conducting efficient spectroscopic analyses. RefFIT is built upon the academic version developed at the University of Geneva, and our cutting-edge SaaS technology has our scientific model-based approach at its core. We’ve added new enhanced features, making it perfect for engineers, scientists, and students conducting research, optimizing industrial processes, or exploring the world of spectroscopy. Welcome to a new era of spectroscopic analysis with RefFIT!
