A data-driven approach to secondary color analysis

The correction of secondary axial color is a major design driver in broadband optical systems requiring a careful balance between optical performance and the cost of special glasses. Traditional analysis methods often fall short of addressing the true nature of secondary color aberrations in design. We present a unified framework that combines a data-driven approach to dispersion modelling with a simplified, single-term theory of induced secondary color aberrations. This approach provides an accessible and practical description of secondary color effects, enabling deeper understanding and improved material selection for system optimization.
