摘要

This study investigates the design, optimization, and simulation of anti-reflection (AR) coatings for optical glass, focusing on reducing reflectance and enhancing light transmittance across the ultraviolet (UV) and visible spectrum. By employing Ray-Tracing simulation techniques, various thin-film configurations—including single-layer, double-layer, four-layer, and two-layer coatings—were analyzed for their optical properties. These coatings were applied to the glass to determine the most effective combinations for minimizing light reflectance and optimizing visual performance. SnO2 and MgF2 were selected as the coating materials due to their complementary refractive indices, which are crucial for reducing reflectance across a wide wavelength range. The simulation results revealed that bilayer coatings on both sides of the glass outperformed other configurations, particularly at the critical wavelength of 550 nm, where human visual sensitivity peaks. This wavelength-specific optimization is essential for reducing glare and improving the visual clarity of optical surfaces, making these coatings highly applicable in products such as eyeglasses and precision optical instruments. The findings underscore the potential of SnO2/MgF2 coatings in achieving high optical performance, providing a foundation for future developments in anti-reflective technologies aimed at improving visual comfort and clarity.
