cryptonixdgh (Computational Resolution Yield Predictor for Tunable Optical Nanostructures and Integrated Xeno-Diffraction Grating Holography) is an advanced iOS calculator app tailored for the optical and photonic manufacturing industry. It enables engineers and researchers to estimate two critical performance metrics diffraction efficiency and polarization sensitivity of subwavelength nanostructures such as nanogrooves. By entering groove depth, period, incident wavelength, and polarization angle, users can simulate the optical behavior of metasurfaces and holographic elements with precision. The app features a clean UI with icon-based buttons, real-time validation, and an immersive full-screen background, offering a fast, reliable way to guide early-stage design or optimize nanofabrication parameters for next-generation optical devices.
