Abstract
The process of making laterally graded interference filters has been reanalyzed. A simple and consistent picture arises if one applies a constant electric field perpendicular to the etch current instead of a constant current. The system is quantitatively modeled by means of a pure ohmic equivalent circuit model. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
