Synopsys CODE V is a powerful tool for designing coronagraphs, essential for astronomical instruments studying exoplanets and faint celestial objects near bright stars. Its advanced optical modeling and optimization features enable precise shaping of coronagraph masks and mirrors to minimize stray light and achieve high contrast. CODE V’s robust diffraction analysis accurately predicts the system’s ability to suppress starlight while maintaining image quality. The solution also supports tolerance analysis to account for manufacturing and alignment errors, ensuring reliable performance. With CODE V, designers can create efficient, high-performing coronagraphs that push the boundaries of space observation and exploration.
