digitradetarb

What is it about?

digitradetarb (Digital Gradient Tuning via Refractive Adjustment Through Etching for Advanced Radiative Behavior) is a precision iOS calculator built for specialists in the Optical and Photonic Manufacturing field. The app estimates the effective refractive index of a functional layer that has undergone nano or micro-scale etching or patterning, enabling users to understand and control light behavior in advanced structures like metasurfaces, augmented reality optics, and holographic films. By entering the base and etched refractive indices along with etch depth and total thickness, engineers and researchers can instantly compute the adjusted index value. Featuring a clean, image-enhanced interface with real-time input validation, a full-screen technical background, and reset functionality, digitradetarb offers both accuracy and ease, making it an essential tool for next-generation optical design and surface engineering.
