Abstract
This study presents the development of a laser-based system designed to accurately measure the refractive index of lenses under zero-stress conditions. Using pig lenses as biological analogs for human lenses, the system calculates refractive properties by analyzing the behavior of laser beams passing through the lens. The refractive index is determined through an automated system that processes the intensity profile of the laser beam, applying Snell’s law to compute angles of refraction. To replicate physiological conditions, the lenses are immersed in phosphate-buffered saline (PBS). The results demonstrate that the system effectively measures refractive properties without introducing external stress, providing valuable benchmark data for optomechanical modeling. Additionally, the study highlights the system's capability to generate precise gradient refractive index (GRIN) profiles, offering potential applications in ocular disease research and the development of therapeutic interventions.
