The Focusing Optics X-ray Solar Imager (FOXSI) is a sounding rocket experiment designed to observe X-ray emission from medium-to-large solar flares. Its primary goal is to study particle acceleration in the solar atmosphere by capturing high-resolution, real-time X-ray data during solar flare events. FOXSI uses seven focusing Wolter-I optics, each composed with its corresponding mirrors and detectors to achieve precise imaging of solar flares. As part of the FOXSI project, we are working on an improved ray tracing software to model the reflectivity of the optics. The software is one part of a suite of softwares used to align the Wolter-I optics during integration. In this presentation, we focus on a specific module that computes the three-dimensional reflectivity surfaces as a function of incident angle and photon energy, which is crucial for modeling the behavior of X-rays as they interact with the mirrors. The reflectivity module generates graphs which provide insight into the physical parameters that affect the mirror's reflectivity, including film thickness, interface roughness, surface roughness, and material density. While the original ray tracing code was completed in Python, we are rewriting it in Julia to improve its efficiency.
