PhasFocalix

PhasFocalix is a precision tool for optical engineers and photonics researchers that transforms metasurface phase design parameters into clear performance insights. By combining analytical inversion of the metalens phase profile with intelligent phase unwrapping, the app delivers accurate estimates of effective focal length and focusing efficiency directly from user inputs. Its streamlined interface and gradient-styled design make complex lens behavior easy to interpret, while the built-in Strehl ratio–based efficiency metric provides a quick indication of optical quality. Whether for rapid prototyping, academic study, or experimental validation, PhasFocalix offers a reliable way to explore and evaluate flat-lens focal properties on the go. Show More
